Abstract
The object of the present invention is to suppress rebound of a human body when receiving a large impact load accompanying a collision or the like. A back frame member 20 and a seat frame member 10 are individually formed by welding or caulking, and a link member 30 for connecting both is attached to the back frame member 20 and the seat frame member 10 by welding or caulking. Each of the frame members is provided with a cushioning member as a tension structure. Upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the tension of the cushioning member provided as the tension structure lowers to be able to exhibit high damping characteristics.
Claims19
An impact absorbing structure having a cushioning member provided as a tension structure with a tension field formed by being supported on a frame member,
- wherein upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, said frame member deforms in a direction to reduce the tension of said tension structure.
An impact absorbing structure having a cushioning member provided as a tension structure with a tension field formed by being supported on a frame member,
- wherein at least a part of said cushioning member is provided in a state of contracting in a tangential direction of said cushioning member in a normal state, and upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the contraction state of said cushioning member is released.
An impact absorbing structure having a cushioning member provided as a tension structure with a tension field formed by being supported on a frame member,
- wherein at least a part of said cushioning member is provided in a state of contracting in a tangent direction of said cushioning member in a normal state, and
- wherein upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the contraction state of said cushioning member is released, and said frame member deforms in a direction to reduce the tension of said tension structure.
A seat structure, comprising:
- a back frame member;
- a seat frame member;
- and
- a cushioning member provided as a tension structure with a tension field formed by being supported on each of said frame members,
- wherein upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, at least one of said frame members deforms in a direction to reduce the tension of said tension structure.
A seat structure, comprising:
- a back frame member;
- a seat frame member;
- and
- a cushioning member provided as a tension structure with a tension field formed by being supported on each of said frame members,
- wherein at least a part of said cushioning member is provided in a state of contracting in a tangential direction of said cushioning member in a normal state, and upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the contraction state of said cushioning member is released.
A seat structure, comprising:
- a back frame member;
- a seat frame member;
- and
- a cushioning member provided as a tension structure with a tension field formed by being supported on each of said frame members,
- wherein at least a part of said cushioning member is provided in a state of contracting in a tangent direction of said cushioning member in a normal state, and
- wherein upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the contraction state of said cushioning member is released, and said frame member deforms in a direction to reduce the tension of said tension structure.
