Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vehicle seat provided with an ottoman.

[0002]

2. Description of the Related Art As a technique for moving an ottoman in conjunction with the movement of a seat back, a conventional technique as shown in FIG. 8 (Japanese Patent Application Laid-Open No. H6-154054) is known. In this seat structure, when the backrest 03 is tilted backward, the rod 05 that is link-supported with the backrest 03 is pushed forward below the seating part 02, and the ottoman part 04 that is link-supported with the rod 5 is moved forward. It has a structure to swing out.

[0003]

However, in such a conventional interlocking structure, when the backrest angle is moved, the ottoman angle is uniquely determined, so that the backrest angle that matches the occupant's physique and taste is preferred. There is a problem that it is difficult to provide the relationship between the angle and the Ottoman angle.
The present invention has been made in view of such a conventional problem, and in a vehicle seat provided with an ottoman interlocking with a seat back, the position of the ottoman can be independently adjusted in angle from the interlocking position. Another object of the present invention is to solve the conventional problems by enabling the ottoman to return to the substantially same storage position in conjunction with the seat back regardless of the independent angle adjustment position of the ottoman.

[0004]

According to a first aspect of the present invention, there is provided a vehicle seat provided with an ottoman interlocking with a seat back, wherein the position of the ottoman is independent of the interlocking position. The angle can be adjusted. According to a second aspect of the present invention, in the vehicle seat according to the first aspect, the ottoman can return to substantially the same storage position in conjunction with the seat back regardless of the independent angle adjustment position. According to a third aspect of the present invention, in the vehicle seat according to the first or second aspect, the interlocking operation of the ottoman can be achieved by a mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a vehicle seat of an embodiment, FIG. 2 is a side view of a mechanism of the vehicle seat of the embodiment, and FIG. 3 is a perspective view of a mechanism of the vehicle seat of the embodiment. It is. First, the configuration will be described with reference to FIGS.
In the present embodiment, the seat back 100 and the cushion 10
Ottoman 102 attached to front end of cushion
A dial 103 for independently adjusting the ottoman and a reclining lever 104 for tilting the seat back forward and backward are provided on the side surface of the cushion.

In the seat back 100, a back frame 105 is attached to a base frame 108 via a reclining 107, and the seat back 100 can be tilted forward and backward by turning the reclining 107 by operating a reclining lever 104.

The base frame 108 is a cushion 101
The inner cushion frame 106 is also supported, and the base frame 108 is fixed to the floor 110 by slide rails 109 at the lower part. An ottoman frame 115 is provided inside the ottoman 102, and the ottoman frame 115 is configured such that a rotation shaft 117 provided on an upper portion of the ottoman frame 115 is supported by arms 116 provided on both side surfaces of the cushion frame 106. As a result, it is rotatably attached to the front end of the cushion frame 106.

The shaft 118 and the bevel gear A119 provided on the ottoman frame 115 are rotated by the dial 103, and the ottoman frame 115 has a ball screw 113 and a bevel gear B1 which are orthogonal to the shaft 118.
20 and a bevel gear A119 is provided with a bevel gear B12.
It is engaged with 0. A nut 114 fitted into the ball screw 113 is rotatably attached to the link B112 at a point B, and the other end of the link B112 is rotatably fixed to a link A111 fixed to a lower portion of the back frame 105 at a point A. Thus, the lower part of the ottoman 102 is supported. When the dial 103 is rotated, the bevel gear A1
19. The ball screw 113 rotates via the bevel gear B120, and the nut 114 moves in the axial direction of the ball screw 113.

When the seat pack 100 is in the upright position, the ottoman 102 is set to a storage position in which the ottoman 102 hangs down in front of the cushion 101, and the ball screw 113 is also mounted in a hang-down direction.

Next, the operation will be described. 4 to 7 are side views for explaining the movement of the ottoman 102 according to the embodiment of the present invention. First, in FIG. 4, when the back frame 105 is tilted backward by the rotation of the reclining 107, the link A111
As a result, point A moves forward. By this movement, the point B of the nut 114 supporting the lower part of the ottoman 102 via the link B112 also moves forward, and the ottoman 102 is swung out to the use position.

Next, by turning the dial 103 in FIGS. 5 and 6, the ball screw 113 is rotated around the axis via the bevel gear A119 and the bevel gear B120, and the nut 114 is turned to the side to be raised as shown in FIG. If the ottoman 102 is 1
When the ottoman 102 moves to the position 02a and turns the nut 114 downward as shown in FIG.
The occupant can adjust the relationship between the seatback angle and the ottoman angle according to the physique or preference because the angle of the ottoman 102 can be adjusted independently of the interlocking position with the seatback 100 by moving to the position Can be.

When the back frame 105 is tilted forward to the original position by the rotation of the reclining 107 in FIG.
11 moves the point A backward. By this movement, the point B of the nut 114 supporting the lower part of the ottoman 102 via the link B also moves rearward, and the ottoman 1
02 is returned to the storage position. At this time, the ball screw 11
3 is in a hanging position, so that the ottoman 102 can be adjusted to an independent hanging position regardless of the position of the nut 114 with respect to the ball screw 113 even if the ottoman 102 is adjusted independently before being stored. can do.

Further, this embodiment has the following effects in addition to the above effects. Ottoman 102
When the ottoman 102 is used for the second and subsequent times, there is no need to re-adjust the relationship between the seatback angle and the ottoman angle when the ottoman angle is used for the second and subsequent times.

[0014]

As described above, according to the present invention, according to the present invention, in a vehicle seat provided with an ottoman interlocking with the seat back, the position of the ottoman can be adjusted independently of the interlocking position. Thereby, it is possible to provide the seat back angle and the ottoman angle according to the occupant's physique and preference with a slight adjustment, and furthermore, regardless of the independent angle adjustment position of the ottoman, the ottoman is almost interlocked with the seat back. By being able to return to the same storage position, it is possible to provide an advantageous ottoman with a simple mechanism.
