Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a vehicle seat equipped with a thigh support device, and more specifically to a vehicle seat (automobile seat) equipped with a thigh support device (thigh support device). This relates to improvement of the cushion structure.

(Prior Art) As this type of vehicle seat, those shown in FIGS. 5 and 6 are known. In the figure, 1 is a seat cushion of an automobile seat, and a seat bag (not shown) is attached to the rear end surface. A cushion member 2 of this seat cushion 1 is covered with a skin member 3 and placed on a cushion support member 4. This cushion member 2 includes a thigh support portion 5 and a buttocks support portion 6.
The thigh support part 5 is pulled upwardly with respect to the buttocks support part 6 by the thigh support device 7. This thigh support device 7 is provided with a pair of left and right movable plates 8, 8 under the cushion support member 4 on the side of the thigh support part 5, and handles 9, 9 attached to both sides of the seat cushion 1. Therefore, each of the movable plates 8, 8 moves up and down, lifts up the thigh support part 5 on the upper part of the movable plate 8, and supports the thigh of the occupant.

(Problems to be Solved by the Invention) In the automobile seat with the thigh support device having the above configuration, the thigh support portion 5 is pulled upward relative to the buttocks support portion 6 by the thigh support device 7, and accordingly, The skin member 3 that covers the thigh support part 5 is lifted up, but the thigh support part 5 of the cushion member 2 is not attached to the skin because the skin member 3 is integrally molded with other cushion parts and there is no slack in the skin member 3. It was compressed and hardened by the member 3, causing an uncomfortable feeling in the thighs of the occupant, and the thigh support portion 5 did not lift up sufficiently, resulting in insufficient support for the thighs of the occupant.

It was developed to solve the problems associated with this invention, and is for vehicles equipped with a thigh support device that can sufficiently support the thighs of the occupant and provide a cushioned feeling to the thighs of the occupant. The purpose is to provide sheets.

(Means for Solving the Problems) A vehicle seat with a thigh support device according to the present invention has concave grooves formed along the depth direction on both sides and the center of the thigh support part, so that the left and right The left and right thigh support parts are placed on each of the movable plates, and a hanging groove consisting of a deep groove for suspending the skin member is provided at the rear of the thigh support part, and the hanging groove is a thigh support part. A suspension wire is embedded in the lower cushion member, the skin member is tied to the suspension wire, and the left and right thigh support parts are moved up and down independently by each movable plate. It is.

(Function) According to the vehicle seat with the thigh support device according to the present invention, grooves are formed along the depth direction on both sides and the center of the thigh support portion to form the left and right thigh support portions. The left and right thigh supports can be moved up and down independently by each movable plate of the thigh support device, making it easy to lift the left and right thigh supports and supporting the left and right thighs of the occupant. can be performed separately, and the left and right thigh supports can be adjusted according to the occupant's preference.

Furthermore, a suspension groove consisting of a deep groove for suspending the skin member is provided at the rear of the thigh support portion, and the skin member can be suspended and tied to a suspension wire embedded in the cushion member below the suspension portion. Therefore, even if the thigh support part moves up and down, the skin member can be reliably fixed, and the skin member at the rear of the thigh support part will not lift up from the thigh support part.

(Example) An example of this invention is shown in Figures 1 to 4.
This will be explained based on the diagram. In the figure, reference numeral 11 denotes an automobile seat, which is composed of a seat cushion 12 and a seat back 13. In this seat cushion 12, a cushion member 15 covered by a skin member 14 is placed on an outer frame 16, and a thigh support device 17 is mounted below the cushion member 15. The thigh support portion 18 of this cushion member 15 is lifted by the thigh support device 17 . That is, the cushion member 1 is placed on the outer frame 16.
A cushion support member 19 supporting the cushion support member 19 is attached, and the thigh support portion 1 of this cushion support member 19
The movable plate 2 of the thigh support device 17 is on the 8 side.
0 comes into contact with the lower surface of the cushion support member 19.
This movable plate 20 consists of a pair of left and right plates, each of which is movable independently. And the movable plate 20
A rotation shaft 21 that supports the movable plate 20 is provided at the rear end portion, and the rotation of the rotation shaft 21 causes the front end portion of each movable plate 20 to rotate, and the cushion support member 19, that is, the cushion Lift up the thigh support portion 18 of the member 15. The rotation shaft 21 of the movable plate 20 is provided under the boundary between the thigh support portion 18 and the butt support portion 22 of the cushion member 15, and extends horizontally on the outer frame 16 and protrudes from the left and right side surfaces of the seat cushion 12. do.

An operation handle 30 is attached to the left and right protrusions of the rotation shaft 21, and when the operator operates the operation handle 30, the rotation shaft 21 rotates, and the rotation shaft 21 serves as the center of rotation for the movable plate. The front end portion of 20 rotates up and down as shown. The thigh support portion 18 of the cushion member 15 is provided with notches 23 extending in the depth direction on both sides and in the center, forming left and right thigh support portions 18a and 18b. A cutout is also formed at a location in the cushion support member 19 corresponding to the cutout portion 23 of the thigh support portion 18, and when the movable plate 20 on the lower surface of the cushion support member 19 moves up and down, the cushion support member 19 and the thigh support portion 1
8 is lifted up. The cushion member 15 consisting of the thigh support portion 18 and the like is covered by the skin member 14. This skin member 14 is the thigh support part 1
A hanging portion is formed at a location corresponding to the cutout portion 23 of No. 8, and a slack portion 24 is provided between the skin member 14a of the thigh support portion 18 and the other skin member 14b. This slack portion 24 is also formed in a notch 23 between the left and right thigh support portions 18a and 18b of the thigh support portion 18, in which a hanging portion of the skin member 14 is formed. Furthermore, as shown in FIG. 4, a suspension groove 25 consisting of a deep groove for suspending the skin member 14 is provided at the rear portion of the thigh support portion 18. A suspension wire 26 is embedded in the cushion member 15 below the suspension groove 25, and the skin member 14 is tied to the suspension wire 26 via a suspension bag 27.

The automobile seat 11 with the thigh support device according to the above configuration has the thigh support portion 18 of the cushion member 15.
A notch 23 is formed in the depth direction on both sides and in the center so that the left and right thigh support parts 18a, 18b can move separately from the left and right cushion members of the thigh support part 18, and this cushion member 15 A hanging part is formed in the skin member 15 covering the skin member 15 at a location corresponding to the notch part 23 of the thigh support part 18, and a slack part 24 is formed between the skin member 14a of the thigh support part 18 and the other skin member 14b. By providing this, when each movable plate 20 of the thigh support device 17 is operated, the left and right thigh support parts 18a, 18b are respectively lifted to reliably support the thighs of the occupant. Furthermore, the rhinoceros support part 1
8 is not compressed by the skin member 14, so a soft feeling of thigh support can be obtained. In addition, a cutout portion 23 is formed in the thigh support portion 18, and the left and right thigh support portions 1
Since 8a and 18b can be moved respectively, the thigh support part 18 does not come apart from other cushion members, and the appearance is good.
