Description
FIELD OF THE INVENTION
[0001] The present invention generally relates to a webbing guide
for a seatbelt associated with a vehicle seat. In particular, the
webbing guide includes a guide body with a moveable end to adjust a
position of the webbing with respect to the seat.
BACKGROUND OF THE INVENTION
[0002] The widely varying sizes and body-types of vehicle seat
occupants can result in seatbelts associated with such vehicle
seats contacting the use at varying points along the user's body.
In some instances, particularly with respect to shorter occupants,
the webbing positioning can cause uncomfortable contact with the
seat occupant's neck. Other undesirable positions are also possible
based on particular webbing and set configuration, as well as
specific physical aspects of the seat occupant.
[0003] Various assemblies for achieving particular positioning of a
seatbelt webbing with respect to the associated vehicle seat are
available. In particular, some such positioning assemblies include
a vertically moveable D-ring or other such assembly for moving an
upper anchoring point of the webbing vertically up and down along
the B-pillar of the associated vehicle. Other assemblies include
various fixed guides or pass-throughs on the vehicle seat itself.
Notably, such assemblies either fail to adjust the webbing
positioning at all or do not directly address the issue of lateral
positioning of the webbing on the user. Accordingly, further
improvements are desired.
SUMMARY OF THE INVENTION
[0004] According to one aspect of the present invention, a webbing
guide for a vehicle seat includes a base defining a length between
a first end and a second end and a guide body coupled with the base
and defining a guide channel extending at least partially along a
length of the base. A first end of the guide channel is disposed
adjacent the first end of the body and is moveable toward and away
from the second end of the body.
[0005] According to another aspect of the present invention, a
vehicle seat includes a seatback and a webbing guide. The webbing
guide includes a base coupled with the seatback and defining a
length between a first end and a second end and a guide body
coupled with the base and defining a guide channel extending along
a length of the base. A first end of the guide channel is moveable
along at least a portion of the length of the base.
[0006] According to another aspect of the present invention, a
vehicle includes a vehicle seat coupled within the vehicle and
including a seatback. The vehicle further includes a webbing
coupled with the vehicle and associated with the vehicle seat and a
webbing guide. The webbing guide has a base coupled with the
seatback and defining a length between a first end and a second end
and a guide body coupled with the base and defining a guide channel
extending along a length of the base and receiving the webbing
therethrough. A first end of the guide channel is moveable along at
least a portion of the length of the base to adjust a position of
the webbing with respect to at least a portion of the seatback.
[0007] These and other aspects, objects, and features of the
present invention will be understood and appreciated by those

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] For purposes of description herein, the terms "upper,"
"lower," "right," "left," "rear," "front," "vertical,"
"horizontal," "interior," "exterior," and derivatives thereof shall
relate to the invention as oriented in FIG. 1. However, it is to be
understood that the invention may assume various alternative
orientations, except where expressly specified to the contrary. It
is also to be understood that the specific devices and processes
illustrated in the attached drawing, and described in the following
specification are simply exemplary embodiments of the inventive
concepts defined in the appended claims. Hence, specific dimensions
and other physical characteristics relating to the embodiments
disclosed herein are not to be considered as limiting, unless the
claims expressly state otherwise. Additionally, unless otherwise
specified, it is to be understood that discussion of a particular
feature of component extending in or along a given direction or the
like does not mean that the feature or component follows a straight
line or axis in such a direction or that it only extends in such
direction or on such a plane without other directional components
or deviations, unless otherwise specified.
[0022] Referring to FIG. 1, reference numeral 10 generally
designates a webbing guide for a vehicle seat 12 (FIG. 3). Webbing
guide 10 includes a base 14 defining a length 16 between a first
end 18 and a second end 20. Webbing guide 10 further includes a
guide body 22 coupled with the base 14 and defining a guide channel
24 extending at least partially along the length 16 of base 14. A
first end 18 of the guide channel 24 is moveable toward and away
from the second end 20 of base 14.
[0023] As shown in FIG. 3, webbing guide 10 may be coupled with a
vehicle seat 12 that includes a seatback 28 and can be used to
adjust the path of a webbing 44 corresponding with vehicle seat 12.
As further shown in FIG. 3, webbing guide 10 can be coupled with
seatback 28 and can be positioned such that the above-mentioned
movement of first end 26 of guide channel 24 can be used to adjust
the positioning of webbing 44, including the related positioning of
an edge 45 thereof with respect to an adjacent headrest 46. It is
further noted that such adjustment may allow a user to adjust the
positioning of the webbing 44 and the corresponding edge 45 to a
desired position with respect to the user to, for example, provide
increased comfort for the user by moving edge 45 away from the
user's neck.
[0024] As shown in the related-art depiction in FIG. 1, the size,
particularly the height, of a user or occupant of vehicle seat 2
without an adjustable webbing guide can result in uncomfortable or
otherwise disadvantageous positioning of an edge 7 of seatbelt
webbing 1 with respect to the user's neck and/or head. As
illustrated in FIG. 1, even vehicle seat 2 arrangement that
includes a fixed webbing guide 3 thereon may still position webbing
1 in a position that causes uncomfortable interaction with various
portions of the user's body, including the neck and head. This can
be particularly pronounced when the user's head is positionable
below the headrest 8 of vehicle seat 2, as illustrated, the webbing
guide 3 being at a fixed position with respect to headrest 8.
[0025] Accordingly, by providing the webbing guide 10, described
herein, a position of webbing 44 can be adjusted with respect to
headrest 46, per the desires of the occupant of seat 12. As
depicted in FIG. 4, the above-described first end 26 of guide
channel 24 can be defined on a pin 38 that can be selectively and
removeably received in one of a plurality of holes 40 within and
distributed along guide body 22, including at regular intervals
therealong, so as to be moveably disposed with respect thereto. As
shown, the first end 26 of guide channel 24 defined on pin 38 can
be a side of pin 38 adjacent to edge 45 of webbing 44 such that
first end 26 can limit the lateral movement of webbing 44 within
guide channel 24 (i.e. in direction 32, as indicated in FIG. 3). In
this manner the user, by repositioning pin 38 among the available
holes 40 can change a lateral limit of the travel of webbing 44
within guide channel 24. As further shown in
[0026] FIG. 3, the positioning of webbing guide 10 on seatback 28
can be such that when webbing 44 is received within guide channel
24 it is moved away from headrest 46 in lateral direction 33 from
its natural position with respect thereto. In this manner, the
tension of webbing 44 applied by the seatback mechanism associated
therewith can maintain edge 45 of webbing 44 in general contact
with edge 45 of guide channel 24, as defined by pin 38.
[0027] In this manner, the user can change the positioning of
webbing in directions 32 and 33 by appropriately assembling pin 38
within a desired one of holes 40 with webbing 44 positioned on a
laterally outward side thereof (i.e. away from headrest 46). As
shown in FIG. 4, pin 38 is assembled with one of holes 40 that is
closest to first end 18 of base 14 such that webbing 44 is moved
outwardly away from headrest at a position relatively closer to
headrest 46 than provided by the reaming ones of holes 40. It is
noted that a further lateral position closer yet to headrest 46 can
be provided by removing pin 38 and allowing edge 45 of webbing 44
to contact and end of guide channel 24 adjacent to first end 18 of
base 14, such that first end 26 of guide channel 24 is defined by
the end of guide channel 24. As further shown in FIG. 2, guide body
22 can include a slot 30 therein to allow removal of webbing 44
therefrom. This can be advantageous to allow aftermarket assembly
of webbing guide 10 with a vehicle seat 12, or to allow a user to
remove webbing 44 from webbing guide 10 such that webbing 44 can be
in its natural position. In the embodiment depicted in FIG. 3, as
well as in other embodiments described herein, such a slot may be
omitted such that the webbing 44 is generally permanently received
within guide channel 24.
[0028] As further shown in FIG. 4, a series of secondary holes 42
can be positioned within base 14 so as to be generally aligned with
holes 40 such that when pin 38 is assembled with webbing guide 10
it engages with one of holes 40 and the corresponding one of
secondary holes 42 to provide stability for the assembly of pin 38
with webbing guide 10. In one aspect, pin 38 may form a press-fit
engagement with holes 42, while generally freely passing through
holes 40 to aid in assembly and retention thereof with webbing
guide 10.
[0029] It is noted that the depiction of webbing guide 10 in FIG. 4
is schematic in nature and reflects the overall construction of
webbing guide 10 as illustrated in FIG. 2 in a conceptual manner,
particularly with respect to the shape and configuration of guide
channel 24, which is shown in FIG. 2 as extending in an arcuate
manner. For sake of simplicity of illustration, the depiction of
webbing guide 10 in FIG. 4, as well as FIGS. 5-7 are depicted with
guide channel 24 extending in a generally straight manner, and with
portions of base 14 omitted for clarity of illustration. It is
noted that, further, any of the additional embodiments shown in
FIGS. 5-7, as described further below, as well as FIG. 4, can be
adapted to be configured as shown in FIG. 2 or in other
configurations developed to match the geometry of seatback 28,
headrest 46, as well as the location of other features associated
with webbing 44 including the location of a D-ring 36 or other
anchoring structures.
[0030] Turning now to FIG. 5 a further variation of the
above-described webbing guide is illustrated. In particular,
webbing guide 110 includes a further plurality of aligning holes
140 and secondary holes 142 adapted to receive pin 138 in various
locations along guide channel 124 to establish an end 126 of guide
channel 124 at varying positions with respect to second end 120 of
base 114. As illustrated, pin 138 may include a pull tab 148 along
an upper portion thereof to assist a user in grasping pin, for
example, for removal of pin 138 from hole 140. Further, pin 138 is
illustrated with a snap feature 150 disposed at an end thereof
opposite tab 148. In one aspect, snap feature 150 can be a spring
tab that can be outwardly biased, such as into the position shown
in FIG. 5. Secondary holes 142 can be configured to accept snap
feature 150 therethrough, under compression thereof, while allowing
snap feature 150 to return to its outwardly-biased position upon
assembly with secondary holes 142. This arrangement can,
accordingly, provide for additional retentive force of pin 138 with
guide body 122, to prevent, for example, intentional removal of
pin.
[0031] FIGS. 6 and 7 show a further variation of webbing guide 210
that includes a generally permanently assembled pin 238 with
respect to guide body 222, pin 238 being a spring pin retained
within a slot 240 extending along a portion of the length 216 of
base 214 such that pin 238 is slidable with respect thereto in an
adjustment direction 232 along a portion of guide channel 224. In
this embedment, pin 238 can be configured with a pull tab 248 at an
upper end thereof and disposed outside of guide body 222 for access
thereto by a user. Further, pin 238 can include a flange 256
received within guide channel 224 and oversized with respect to
slot 240 such that flange 256 serves to retain pin 238 in assembly
with guide channel 224. A lower portion 252 of pin 238 extends away
from flange 256 opposite of pull tab 248 such that an end 254 of
pin defined thereon is selectively engageable with one of secondary
holes 242 positioned opposite guide channel 224 from slot 240. In
an arrangement, lower portion 252 may be integrally or otherwise
joined with pull tab 248 and may, further, be spring biased in a
direction away from flange 256 in a direction opposite slot 240
such that, when aligned with one of secondary holes 242, lower
portion 252 is urged downwardly and into engagement therewith. Such
a biasing force also serves to retain flange 256 in an engaged
manner with an interior of guide channel 224 adjacent slot 240.
[0032] In this arrangement, if a user desires to adjust the
positioning of first end 226 of guide channel 224, the user may
pull upwardly in direction 258 on pull tab 248 to pull lower
portion 252 of pin 238 from out of engagement with the particular
secondary hole 242. In this arrangement, pin 238 is moveable
laterally in a direction 232 with respect to guide channel 224. By
such lateral movement of pin 238, the user can bring lower portion
252 of pin 238 into alignment with another one of secondary holes
242, whereupon pull tab 248 can be released, allowing the spring
biasing of flange 256 with respect to lower portion 252 to force
lower portion 252 into engagement with such secondary hole 242. In
this arrangement, pin 238 is, thereby, retained in another position
with respect to slot 230 and first end 226 of guide channel 224 is
maintained in the desired position for contact with edge 245 of
webbing 244, and corresponding adjustment thereof
[0033] A further embodiment of webbing guide 310 is illustrated in
FIGS. 8-11. In this embodiment, base 314 is a rigid element
configured for attachment to a portion of seatback 328, as
illustrated in FIG. 9, adjacent to the path of webbing 344.
Further, guide body 322 is provided as a strap, or another section
of webbing itself, having a first end 360 generally fixedly coupled
to base 314 adjacent the first end 318 thereof. As shown in FIG. 8,
as well as in the cross- sectional views of FIGS. 10 and 11, first
end 360 of guide body 322 can be fixed with base 314 with
engagement of an enlarged or doubled-over portion of the strap at
first end 360 into a slot 366 in base 314 having a size greater
than the strap itself but smaller than the doubled-over portion at
end 360. The opposite second end 362 of guide body 322 can engage
with another slot 366 adjacent second end 320 of base 314 that is
configured to adjustably receive guide body 322 therein. As
depicted in FIGS. 10 and 11, such a slot 366 can be configured in a
similar manner to available adjustable couplings for webbings and
the like. In this manner, guide body 322 defines an adjustable loop
368 that can be extended, that can be extended, as shown in FIGS.
8- 10, and can further be retracted by pulling on end 362, as shown
in FIG. 11.
[0034] When receiving webbing 344, webbing 344 can pull on guide
body 322 to extend the loop 368 away from second end 320 of base
314, including beyond first end 318 thereof as depicted in FIGS.
8-10. In this manner, the first end 326 of guide channel 324
defined through loop 368 can be the upward most portion of loop 368
with which edge 345 engages (or the farthest portion of loop 368
with respect to first end 318). As shown in FIG. 11, when loop 368
is tightened, edge 345 of webbing 344 is urged in direction 332,
thereby altering the portion of loop 368 defining first end 326 of
guide channel 324, as shown in FIG. 11. Such movement of webbing
344 in direction 332 can serve to adjust the position of webbing
344 with respect to seatback 328 and/or headrest 346, resulting in
repositioning thereof with respect to a user occupying seat 312, in
a manner similar to that which is discussed above.
[0035] It is to be understood that variations and modifications can
be made on the aforementioned structure without departing from the
concepts of the present invention, and further it is to be
understood that such concepts are intended to be covered by the
following claims unless these claims by their language expressly
state otherwise.
[0036] For purposes of this disclosure, the term "coupled" (in all
of its forms, couple, coupling, coupled, etc.) generally means the
joining of two components (electrical or mechanical) directly or
indirectly to one another. Such joining may be stationary in nature
or movable in nature. Such joining may be achieved with the two
components (electrical or mechanical) and any additional
intermediate members being integrally formed as a single unitary
body with one another or with the two components. Such joining may
be permanent in nature or may be removable or releasable in nature
unless otherwise stated.
