Abstract

A seat cushion adjuster in one aspect of the present disclosure comprises at least one bracket, at least one slider, at least one first interposing member, and at least one second interposing member. The slider is inserted into an inner hollow portion of the bracket. The slider comprises a base plate part of a plate shape and a pair of raised parts. The pair of raised parts is raised from a pair of ends of the base plate part so as to be raised with respect to one surface of the base plate part. The first interposing member is disposed between an inner wall of the bracket and the slider. The second interposing member is disposed between the inner wall of the bracket and the slider so as to face the first interposing member.

First claim

What is claimed is:

1. A seat cushion adjuster comprising:
at least one bracket configured to be secured to a first one of a cushion body part and a cushion adjustable part, the cushion body part comprising a first seating surface, the cushion adjustable part comprising a second seating surface and being arranged in an arrangement direction pre-specified with respect to the cushion body part, and the at least one bracket comprising an inner wall configured to provide an inner hollow portion extending in the arrangement direction;
at least one slider configured to be secured to a second one of the cushion body part and the cushion adjustable part, the second one being different from the first one, the at least one slider being inserted into the inner hollow portion of the at least one bracket, the at least one slider comprising:
a base plate part of a plate shape comprising a pair of ends that extends in the arrangement direction and that faces each other; and
a pair of raised parts raised from the pair of ends of the base plate part so as to be raised with respect to one surface of the base plate part,

wherein the base plate part and the pair of raised parts provide a concave portion;
at least one first interposing member that comprises a convex portion disposed inside the concave portion and that is disposed between the inner wall of the at least one bracket and the at least one slider; and
at least one second interposing member that comprises a concave region accommodating the at least one slider therein and that is disposed between the inner wall of the at least one bracket and the at least one slider so as to face the at least one first interposing member.

2. The seat cushion adjuster according to claim 1 , wherein the at least one bracket has a tubular shape.

3. The seat cushion adjuster according to claim 1 , wherein the at least one first interposing member comprises at least one sliding projection protruding toward the at least one slider.

4. The seat cushion adjuster according to claim 3 , wherein the at least one sliding projection comprises a plurality of sliding projections.

5. The seat cushion adjuster according to claim 1 , wherein the at least one first interposing member comprises at least one supporting protrusion potion protruding toward the at least one bracket.

6. The seat cushion adjuster according to claim 5 , wherein the at least one supporting protrusion portion comprises a plurality of supporting projections.

7. The seat cushion adjuster according to claim 1 , wherein the at least one second interposing member comprises at least one sliding projection protruding toward the at least one slider.

8. The seat cushion adjuster according to claim 7 , wherein the at least one sliding projection comprises a plurality of sliding projections.

9. The seat cushion adjuster according to claim 1 , wherein the at least one second interposing member comprises at least one supporting protrusion portion protruding toward the at least one bracket.

10. The seat cushion adjuster according to claim 9 , wherein the at least one supporting protrusion portion comprises a plurality of supporting projections.

11. The seat cushion adjuster according to claim 1 , wherein the at least one bracket comprises a plurality of brackets, wherein the at least one slider comprises a plurality of sliders, wherein the at least one first interposing member comprises a plurality of first interposing members, and wherein the at least one second interposing member comprises a plurality of second interposing members.

12. A seat comprising:
a cushion body part comprising a first seating surface;
a cushion adjustable part comprising a second seating surface and arranged in an arrangement direction pre-specified with respect to the cushion body part;
at least one bracket secured to a first one of the cushion body part and the cushion adjustable part, the at least one bracket comprising an inner wail configured to provide an inner hollow portion extending in the arrangement direction;
at least one slider secured to a second one of the cushion body part and the cushion adjustable part, the second one being different from the first one, the at least one slider being inserted into the inner hollow portion of the at least one bracket, the at least one slider comprising:
a base plate part of a plate shape comprising a pair of ends that extends in the arrangement direction and that faces each other; and
a pair of raised parts raised from the pair of ends of the base plate part so as to he raised with respect to one surface of the base plate part,
wherein the base plate part and the pair of raised parts provide a concave portion;

at least one first interposing member that comprises a convex portion disposed inside the concave portion and that is disposed between the inner wall of the at least one bracket and the at least one slider; and
