Abstract

A seat back of a seat includes: a seat back frame; a front side elastic member positioned on a user side; a rear side elastic member disposed more rearward than the front side elastic member is; and a pressure receiving member disposed at a rear of the rear side elastic member. The rear side elastic member has a lower resilience than the front side elastic member. The pressure receiving member supports the front side elastic member and the rear side elastic member while being supported by the seat back frame.

First claim

What is claimed is:

1. A seat comprising a seat back, the seat back including:
a seat back frame;
a front side elastic member positioned on a user side of the seat back frame;
a pair of rear side elastic members which have a lower resilience than a resilience of the front side elastic member, and which are disposed more rearward than the front side elastic member; and
a pressure receiving member disposed behind the rear side elastic members, the pressure receiving member configured to, while being supported by the seat back frame, support the front side elastic member and the rear side elastic members, wherein:
the rear side elastic members are configured to suppress vibrations of the seat back frame or vibrations of the pressure receiving member from being transmitted to the front side elastic member,
the pair of rear side elastic members comprises a first rear side elastic member disposed at a first side of a center of the seat back in a width direction, and a second rear side elastic member disposed at a second side of the center of the seat back in the width direction, and
a gap is provided between the first rear side elastic member and the second rear side elastic member.

2. The seat according to claim 1 , wherein the front side elastic member is formed of a first urethane material having a first resilience, and
the rear side elastic members are formed of another urethane material having a lower resilience than the first resilience of the first urethane material of the front side elastic member.

3. The seat according to claim 1 , wherein the rear side elastic members comprise at least one rubber sheet.

4. The seat according to claim 1 , wherein a plate, which is harder than the front side elastic member and the rear side elastic members, is disposed between the front side elastic member and the rear side elastic members.

5. The seat according to claim 1 , wherein the seat comprises a side support disposed at a side of one of the rear side elastic members, and a gap is provided between said one of the rear side elastic members and the side support.

6. The seat according to claim 1 , wherein the seat comprises a side support disposed at a side of one of the rear side elastic members, and the side support includes:
a user side elastic member positioned on the user side and having a side support first resilience; and
a frame side elastic member which has a lower resilience than the side support first resilience of the user side elastic member, and which is disposed between the user side elastic member and the seat back frame.

7. The seat according to claim 6 , wherein
the front side elastic member and the user side elastic member are configured from a same material, and
the rear side elastic members and the frame side elastic member are configured from a same material.

8. A vehicle comprising a seat having a seat back, the seat back including:
a seat back frame;
a front side elastic member positioned on a user side of the seat back frame;
a pair of rear side elastic members which have a lower resilience than the front side elastic member and which are disposed more rearward than the front side elastic member; and
a pressure receiving member configured to, while being supported by the seat back frame, support the front side elastic member and the rear side elastic member at a rear of the rear side elastic members, wherein:
the pair of rear side elastic members are configured to suppress vibrations of the seat back frame or the pressure receiving member from being transmitted to the front side elastic member,
the pair of rear side elastic members comprises a first rear side elastic member disposed at one side of a center of the seat back in a width direction, and a second rear side elastic member disposed at another side of the center of the seat back in the width direction, and
a gap is provided between the first rear side elastic member and the second rear side elastic member.

9. A seat comprising a seat back, the seat back comprising:
a seat back frame;
a front side elastic member positioned on a user side of the seat back frame and having a first resilience;
a rear side elastic member disposed behind the front side elastic member and having a lower resilience than the first resilience of the front side elastic member; and
a pressure receiving member disposed behind the rear side elastic member, the pressure receiving member configured to, while being supported by the seat back frame, support the front side elastic member and the rear side elastic member,
wherein:
the rear side elastic members are configured to suppress vibrations of the seat back frame or vibrations of the pressure receiving member from being transmitted to the front side elastic member,
the seat comprises a side support disposed at a side of the rear side elastic member, and a gap is provided between the rear side elastic member and the side support, and
the front side elastic member abuts against the side support when the seat back is viewed from above.

10. The seat according to claim 9 , wherein the side support includes:
a user side elastic member positioned on the user side and having a side support first resilience; and
a frame side elastic member which has a lower resilience than the side support first resilience of the user side elastic member, and which is disposed between the user side elastic member and the seat back frame.

11. The seat according to claim 9 , wherein
the front side elastic member and the user side elastic member are configured from a same material, and
the rear side elastic member and the frame side elastic member are configured from a same material.
