Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a seat device, and more
particular to a seat device applied to office furniture.
[0003] 2. Description of Related Art
[0004] Among great population of labor staying in office, many
people have to seat on office chairs for quite a long time to face
the computers during working. Usually, an office chair with a flat
seat device makes a person seat thereon feel uncomfortable, causes
the spine ache, and leads to inaccurate sitting posture, which
might incur various illness. Although some seat devices of
conventional office chairs are designed into curved surface, the
simple structure of the curved surface is still insufficient to
ease the tiredness and to correct a user's sitting posture.
SUMMARY OF THE INVENTION
[0005] A main objective of the present invention is to provide a
seat device that provides comforting and correcting
capabilities.
[0006] To achieve the foregoing objective, the seat device
comprises a bottom board and a top board secured on the bottom
board, where the improvement of the seat device is:
[0007] two recesses defined on the top board and adapted to hold
the hips.
[0008] The two recesses are selectively with round, oval or ellipse
top cross-section.
[0009] The two recesses are arranged symmetrically to a central
line of the seat device at a right side and a left side.
[0010] The bottom board has two meshed ventilating holes aligned
below the two recesses respectively; each of the two meshed
ventilating holes is performed by multiple arc slits in sections
arranged concentrically.
[0011] The seat device is for chair seat.
[0012] The top board has bulged edges at right side, left side and
rear side respectively.
[0013] The two recesses are tapered downward to perform concave
structures.
[0014] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0015] FIG. 1 is a perspective view of one embodiment of a seat
device in accordance with the present invention;
[0016] FIG. 2 is an exploded perspective view of the seat device in
FIG. 1; and
[0017] FIG. 3 is a perspective view of another embodiment of the
seat device in accordance with the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] A seat device in the present invention has a bottom board
and a top board mounted on the bottom board. The top board has two
recesses defined thereon and adapted to partially hold the hip so
that the seat device provides comforting and correcting
efficiency.
[0019] As shown in FIGS. 1 and 2, a preferred embodiment of a seat
device 1 in accordance with the present invention comprises a
bottom board 1 and a top board 2 secured on the bottom board 1. The
top board 2 has two recesses 3 defined thereon and adapted to
partially hold hips. The shape of the recesses 3 is selectively
with round top cross-section. To fit the hips' shapes, the two
recesses 3 are symmetrical to a central line at right side and left
side respectively and are tapered downward to perform concave
structures respectively. For people in different shapes and sizes,
the recesses 3 are selectively with oval or ellipse top
cross-section (as shown in FIG. 3).
[0020] The bottom board 1 has two meshed ventilating holes 4 right
below the recesses 3. Each meshed ventilating hole 4 is performed
by multiple arc slits 41 in sections arranged concentrically. When
a user sits on the seat device, the meshed ventilating holes 4 have
slight deformation corresponding to the recesses 3.
[0021] The top board 2 has a soft cushion (not shown), which also
has two recesses and a curved surface made of soft cloth, to make
people feel comfortable when sitting on the seat device.
Optionally, the soft cushion is a flat surface made of cloth
material, a curved surface made of net texture, a flat surface made
of net texture, a curved surface made of leather, or a flat surface
made of leather, to make people feel comfortable when sitting on
the seat device.
[0022] The top board 2 further has bulged edges 5 at right side,
left side and rear side respectively.
[0023] Although this invention has been described in its preferred
form with a certain degree of particularity, it is understood that
the present invention of the preferred form has been made only by
way of example and that numerous changes in the details of
construction and the combination and arrangement of parts any be
resorted to without departing from the spirit and scope of the
invention.
