Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a vehicle seat.

[0002]

2. Description of the Related Art Conventionally, there is a seat prepared so as to be able to store a leg rest for supporting a lower leg from an occupant's knee to a lower leg.
As such a seat with a leg rest, for example, a seat having a structure disclosed in Japanese Utility Model Laid-Open No. 4-133762 is known. In this prior art, a leg rest main body is disposed at a front edge of a seat cushion, and the leg rest main body is rotatably supported between a supporting position and a storage position by a pivot shaft. The legrest body is provided with a geared motor for rotating the legrest body. In the storage position, the leg rest body hangs down and the upper part forms a part of the seat cushion, while the leg rest body can support the occupant's feet in a substantially horizontal or inclined state in the support position. Things.

[0003] Further, there is a seat prepared so that a footrest for supporting a sole of an occupant can be stored. As such a footrest storage sheet, one having a structure as disclosed in Japanese Utility Model Laid-Open No. 4-92445 is known. In this prior art, a footrest is housed inside a seat portion so as to be able to be pulled out forward.

[0004]

However, in such a conventional seat with leg rest, the leg rest is suspended from the front edge of the seat cushion and stored, so that the height from the floor to the upper surface of the seat cushion is increased. However, there is a problem in that the leg rest cannot be sufficiently long with a low seat, so that only a part of the lower leg of the occupant can be supported.

In the latter conventional footrest storage sheet, the supporting member and the footrest having a length from the knee to the sole of the occupant are stored in the seat so as to be able to be pulled out forward, so that the weight of the occupant is reduced. The rear portion of the cushion corresponding to the lowermost position also penetrates as a storage space, making it difficult to obtain a sufficient thickness, which is not preferable in terms of sitting comfort, and the problem that the connection with the front portion of the cushion is not smooth.

The present invention has been made in view of such a conventional problem, and is provided with a legrest for supporting a lower leg of an occupant, a footrest for supporting a sole of an occupant, or both of them. In, by moving the leg rests from the storage position under the cushion to the use position by the forward moving means and the upward moving means,
It is an object of the present invention to solve the above-described problem by allowing long leg rests capable of widely supporting the lower limbs of an occupant to be taken in and out, and allowing the upper portion of the leg rest to smoothly contact the front portion of the cushion during use.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a vehicle seat having a legrest for supporting a lower leg of an occupant, a footrest for supporting a sole of an occupant, or both. The leg rest, the foot rest, or both can be stored under the cushion.

According to the present invention, in the above-mentioned vehicle seat, the leg rest and / or the footrest are set to the use position by moving forward and vertically.

Further, the present invention provides the above-mentioned vehicle seat, wherein the legrest and / or the footrest are provided with a means for pulling forward from the storage position and a means for raising the legrest or the footrest to the front of the cushion.

Further, according to the present invention, in the vehicle seat, the leg rest and / or the footrest are moved forward and upward by a trajectory rotated from the storage position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a vehicle seat according to the present invention will be described below in detail with reference to the accompanying drawings.

(First Embodiment) FIG. 1 and FIG. 2 are views showing a first embodiment of a vehicle seat according to the present invention. First, the structure will be described. The vehicle seat according to the first embodiment includes a pair of left and right slide rails on a vehicle body floor 20, as shown in a perspective view of FIG. 1 and a detailed side view of a cushion front part of FIG. A seat 23 is fixed via a base frame 22 and a seat cushion 24. A leg rest 26 for supporting a lower leg of an occupant is provided at a lower front end of a seat cushion 24.
The shaft 25a is attached to the leg rest 26a so as to be able to rotate and move the leg rest 26a forward and backward through the slit 27 inside the leg rest 26a. A gear A28a and a gear B29a are attached to the left and right base frames 22 in mesh with each other, and an arm 30a is fixed coaxially to the gear B29a at a point C, and the arm 30a supports the shaft 25a on the left and right.

Next, the operation of the first embodiment will be described. In the stored state, as shown in FIG. 2A, the leg rest 26a is located at the lower front side of the seat cushion 24, and the rear is low, that is, at the rear of the seat cushion 24, the leg rest 26a is located far from the butt of the occupant, thereby providing a comfortable seat. The long leg rest 26a that can widely support the lower limb of the occupant can be stored at a position where the influence of the leg rest is small.

In use, as shown in FIG. 2B, the leg rest 26a is pulled out along the shaft 25a passing through the internal slit 27, and is brought out to the front of the seat cushion 24. Next, as shown in FIG. 2 (c), when the motor or the occupant rotates the gear A28a by power such as turning a dial, the arm 30a coaxial with the gear B29a rotates around the point C, and the arm 30a moves right and left. 30a
The leg rest 26a can be smoothly brought into contact with the front portion of the seat cushion 24 by raising the shaft 25a supported by the seat cushion 24.

(Second Embodiment) FIGS. 3 and 4 show a second embodiment of a vehicle seat according to the present invention. First, the structure will be described. The vehicle seat according to the second embodiment includes a pair of left and right slide rails on a vehicle body floor 20 as shown in a perspective view of FIG. 3 and a detailed front side view of a cushion of FIG. A seat 23 is fixed via a base frame 22 and a seat cushion 24. A leg rest 26 for supporting a lower leg of an occupant is provided at a lower front end of a seat cushion 24.
b is stored, and a footrest 31 for supporting the sole of the occupant is fixed below the leg rest 26b. The left and right shafts 25b are rotatably attached to the leg rest 26b so as to pass through the inside of the leg rest 26b. Gears A are provided on the left and right base frames 22.
28b and gear B29b are engaged with each other, and an arm 30b is coaxially fixed to gear B29b at point C, and arm 30b supports shaft 25b on the left and right.

Next, the operation of the second embodiment will be described. In the stowed state, as shown in FIG. 4A, the leg rest 26b is located at the lower part on the front side of the seat cushion 24, and the rear is low, that is, at the rear part of the seat cushion 24, the leg rest 26b is located farther from the occupant's buttocks to provide a comfortable seat.
