Abstract
A shock absorber for vehicle seat is provided. The shock absorber is suspended on a seat frame so as to elastically support a pad. The shock absorber includes: a plurality of wires that are disposed in parallel to the seat frame, both ends of the wires being locked to the seat frame; and a resinous member that connects the wires to each other, the resinous member having a bent portion, wherein the resinous member is elastically deformable in a direction in which the wires are opposed each other in accordance with a deformation of the bent portion.
Claims18
A shock absorber for vehicle seat, the shock absorber suspended on a seat frame so as to elastically support a pad, the shock absorber comprising:
- a plurality of wires that are disposed parallel to the seat frame and have longitudinally extending portions, both ends of the wires being locked to the seat frame;
- and
- a resinous member that extends in a direction transverse to the longitudinal direction of the wires and connects the longitudinally extending portions of the wires to each other, the resinous member having a bent portion, wherein
- the resinous member includes a first portion that extends in a plane connecting the plurality of wires in the transverse direction,
- the bent portion of the resinous member extends from the plane of the first portion so as to protrude away from the pad in a direction orthogonal to the plane of the first portion, the orthogonal direction being a thickness direction of the pad, and
- the resinous member is elastically deformable along the transverse direction in which the wires are opposed to each other in accordance with deformation of the bent portion.
A shock absorber for a vehicle seat, the shock absorber suspended on a seat frame so as to elastically support a pad, the shock absorber comprising:
- a plurality of wires that are disposed parallel to the seat frame and have longitudinally extending portions, both ends of the wires being locked to the seat frame;
- and
- a resinous member that extends in a direction transverse to the longitudinal direction of the wires and connects the longitudinally extending portions of the wires to each other, the resinous member including:
- a pair of first portions that extend in a plane connecting the plurality of wires in the transverse direction;
- a second portion that is spaced from the pair of first portions in a direction orthogonal to the plane connecting the plurality of wires in the transverse direction, and disposed between the pair of first portions in the traverse direction;
- and
- connection portions that connect the pair of first portions to the second portion in the orthogonal direction, wherein
- the pair of first portions are located between the pad and the second portion in the orthogonal direction, the orthogonal direction being a thickness direction of the pad,
- bent portions are respectively provided between each first portion and each connection portion and between the second portion and each connection portion, and
- the resinous member is elastically deformable along the traverse direction in which the wires are opposed to each other in accordance with a deformation of the bent portion.
A vehicle seat comprising:
- a seat frame;
- a pad that is provided on the seat frame;
- and
- a shock absorber that is suspended on the seat frame so as to elastically support the pad, the shock absorber provided between the seat frame and the pad, the shock absorber comprising:
- a plurality of wires that are disposed parallel to the seat frame have longitudinally extending portions, both ends of the wires being locked to the seat frame;
- and
- a resinous member that extends in a direction traverse to the longitudinal directions of the wires and connects longitudinally extending portions of the wires to each other, the resinous member having a bent portion, wherein
- the resinous member includes a first portion that extends in a plane connecting the plurality of wires in the traverse direction,
- the bent portion of the resinous member extends from the plane of the first portion so as to protrude from the pad in a direction orthogonal to the plane of the first portion, the orthogonal direction being a thickness direction of the pad, and
- the resinous member is elastically deformable along the traverse direction in which the wires are opposed to each other in accordance with deformation of the bent portion.
