Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a vehicle seat with a thigh support device, and more specifically relates to an improvement in the suspension structure of a skin member used in this vehicle seat.

(Prior Art) As this type of vehicle seat (automobile seat), those shown in FIGS. 6 and 7 are known. In the same figure,
Reference numeral 1 denotes an automobile seat, which consists of a seat bag (not shown) and a seat cushion 2. The cushion member 3 of this seat cushion 2 is covered with a skin member 4 and placed on a cushion support member 5.
This cushion member 3 has a pair of left and right thigh support parts 6, 6 and a buttock support part 7, and the thigh support part 6 is pulled upwardly with respect to the buttock support part 7 by a thigh support device 8. This rhino support device 8
has a pair of left and right movable plates 9, 9 under the left and right thigh support parts 6 of the seat cushion 3, and each movable plate is operated by handles (not shown) attached to both sides of the seat cushion 2. The plates 9, 9 move up and down independently, and lift the thigh support parts 6, 6 above each movable plate 9, 9 to support the thighs of the occupant. Therefore, the skin member 4 covering the thigh support portion 6 of the cushion member 3
is hung between the left and right thigh support parts 6, 6 from the left and right thigh support parts 6, 6, and its terminal part 4a is sewn to the tip part 10a of the hanging member 10. This hanging member 10 has a base end 10b attached to a hanging wire 11 disposed between the left and right movable plates 9, 9.

(Problems to be Solved by the Invention) The automobile seat 1 with the thigh support device having the above configuration has the left and right thigh support portions 6, 6 lifted upward relative to the buttocks support portion 7 by the thigh support device 8, Along with this, the thigh support part 6 and the skin member 4 covering it are also lifted. At this time,
The terminal portion 4a of the skin member 4 suspended between the left and right thigh support portions 6 moves upward as the thigh support portion 6 is lifted. Furthermore, when only one of the pair of left and right thigh support parts 6 is lifted, the end portion 4a of the skin member 4 is lifted in the same manner as described above, but the skin covering the other thigh support part 6 that has not been lifted is In the member 4, since the end portion 4a of the skin member moved upward, the tension was loosened and wrinkles were generated, resulting in an unsightly appearance.

This invention was made to solve this problem, and even if only one of the pair of left and right thigh support parts is lifted, the skin member covering it does not wrinkle, and the thigh support device has a good appearance. The purpose is to provide vehicle seats.

(Means for Solving the Problems) A vehicle seat with a thigh support device according to this invention suspends an end of a skin member covering the left and right thigh support portions of a cushion member, and
A suspension member for suspending the terminal is formed of an elastic material having a bifurcated tip, and one tip and the other tip of the suspension member are connected to one end of the skin member and the other end of the skin member. The ends are sewn together.

(Function) According to the vehicle seat with the thigh support device according to the invention, each end of the skin member covering the left and right thigh support parts is sewn to each end of the hanging member in the thigh support part. As a result, even if one thigh support part rises, the sewn part on the side of the other thigh support part does not rise, and wrinkles do not occur in the skin member covering it, resulting in a good appearance.

(Example) An example of this invention is shown in Figures 1 to 5.
This will be explained based on the diagram. In the figure, 11 is a car seat, with a seat back 12 and a seat cushion 13.
It consists of. In this seat cushion 13, a cushion member 15 covered by a skin member 14 is placed on an outer frame 16. This cushion member 15 consists of a pair of left and right thigh support parts 16, 16 and a buttocks support part 17, and each thigh support part 16,1
6 is each movable plate 1 of the thigh support device 18
It is lifted by 9,19.

This thigh support device 18 has a pair of left and right movable plates 19, 19 below the left and right thigh support parts 16, 16 of the cushion member 15, and has a pair of left and right movable plates 19, 19 attached to each handle attached to both sides of the seat cushion 13. Therefore, each movable plate 19, 19 moves up and down independently, and each movable plate 19, 19
The upper thigh support parts 16, 16 are lifted to support the thighs of the occupant.

However, the skin member 14 is attached to the left and right thigh support parts 1.
The terminal portion 14a is suspended between 6 and 16.
That is, the end portions 14a, 14a of the left and right outer skin members 14b, 14b covering the left and right thigh support portions 16, 16, respectively, cover the left and right thigh support portions 16,16.
6 and sewn to the hanging member 20.
This hanging member 20 is made of an elastic material, and has a hanging wire 2 disposed between the left and right movable plates 19, 19.
1, and its left and right tips 20a,
20a is the left and right end portions 14a, 14a of the skin member
are sewn to each. When the skin members 14b on the left and right sides in the figure are lifted up by the thigh support portions 16, the end portions 14a of the skin members 14b on the right side and the tip portions 20a of the hanging members 20 on the right side are connected to each other.
The sewing location between the left skin member 14b and the hanging member 20 moves upward, but the sewing location between the left skin member 14b and the hanging member 20 remains in the same position.

In the automobile seat 11 with a thigh support device having the above configuration, when one movable plate 19 is lifted by the thigh support device 18, the thigh support portion 16 on the side of the movable plate 19 is lifted and covers the thigh support portion 16. Skin member 1
Terminal part 14a of 4b and tip part 20 of hanging member 20
Although the sewn part with a is also moved upward by the elastic force of the hanging member 20, the terminal part 14a of the skin member 14b covering the other thigh support part 16 and the hanging member 20
Since the distal end portion 20a is separated from the sewn location between the lifted skin member 14 and the hanging member 20, the state is maintained as it is. Therefore, even if one thigh support part 16 is lifted, the tension of the skin member 14 covering the other thigh support part 16 does not change, and the appearance is good without wrinkles.

(Effects of the invention) As explained above, according to this invention, the end of the skin member that covers the left and right support parts of the cushion member is suspended, and the suspension member that suspends this end is A simple structure in which the parts are formed from a bifurcated elastic material, and one tip and the other tip of the hanging member are sewn to one end and the other end of the skin member, respectively. As a result, even if one thigh support part is lifted, wrinkles do not occur in the skin member covering the other thigh support part, and a vehicle seat with a thigh support device that has a good appearance can be obtained.
