A shock mitigation seat 10 includes a plurality of individual shock absorbing members 16 resilient to compression from a shock impact. The shock absorbing members 16 are positioned one adjacent another and such that at a certain stage of compression an individual shock absorbing member 16 resiliently deforms and comes into contact with one or more adjacent individual shock absorbing members 16 which thereby increases resistance to further compression. The seat may be incorporated in a shock mitigation system 50 which has at least one sensor operable to detect a force and to provide a feedback signal indicative of the nature of the force and a memory record the incidence and severity of these forces and provides an indication of cumulative forces absorbed.

Provided is a conveyance seat with which the assemblability of a wire member with respect to a seat frame can be improved. A conveyance seat includes a seat frame. The seat frame has: a pair of side frames arranged in side portions of the conveyance seat; and a cross-linking frame cross-linking the pair of side frames, a wire member is disposed between the pair of side frames, the cross-linking frame has a wire receiving portion receiving the wire member, and the wire member is fastened to the wire receiving portion.

A seat back pad 70 has a groove 73 for tucking a skin material therein, formed at borders between a central portion 71 and side portions 72. A hole (slot hole 74) is formed in a bottom of the groove 73 along the groove 73. A tuck-in wire 76 for tucking the skin material in includes a plurality of tuck-in portions 76A provided along the groove 73, and a connecting portion (detour portion 76B) detouring around the hole and connecting the tuck-in portions 76A. With this configuration, when an upper body of an occupant P subsides into a seat back S2 in a rear-end collision of a vehicle, the central portion 71, defined by the groove 73 as a border, is easily and sufficiently moved rearward relative to the left and right side portions 72. Furthermore, the tuck-in wire 76 is not exposed through the hole, and thus adhesion between the seat back pad 70 and the tuck-in wire 76 can be improved.

A seat with an alertness-maintaining device that can efficiently secure a drive source (for example, a motor) when the drive source is internally housed and a vibratory stimulus is imparted to the occupant. The present disclosure relates to a seat with an alertness-maintaining device, the seat being provided with an alertness-maintaining device for imparting physical force to the occupant to promote alertness. A load-supporting portion for supporting the load on the back of the occupant is installed, and a device drive unit for imparting physical force to the occupant, the device drive unit that forms the alertness-maintaining device, is attached to the load-supporting portion. The device drive unit is provided with a drive source and a support member. The support member is attached to the load-supporting portion while grasping a part of the load-supporting portion by a drive source attachment surface portion and a load-supporting portion-clamping piece.

A spring-based seat diaphragm may include at least one support diaphragm component. The at least one support diaphragm component may be transversely coupled to the first structural beam and the second structural beam. The spring-based seat diaphragm may include at least one spring. The at least one spring may be proximate to the at least one support diaphragm component. The at least one spring may be parallel to or positioned transverse to the at least one support diaphragm component between the first primary spreader and the second primary spreader. The at least one spring may include a plurality of bends configured to distribute user weight applied to a cushion installed on the aircraft seat over the spring-based seat diaphragm. The spring-based seat diaphragm may be configured to support an aft portion of the cushion. The first structural beam may be configured to support a forward portion of the cushion.

A vehicle seat includes right and left side frames 10, and an elastic member (cushion spring 20) run between the right and left side frames 10. The right and left side frames 10 include side walls 11 disposed opposite to each other in a lateral direction, and flange portions (upper flange portions 12) respectively extending laterally inward from the side walls 11, and the elastic member is attached to the flange portions.

A seat pan for a vehicle seat. The seat pan includes a rear portion and a front portion. The seat pan includes a flexible area arranged between the rear portion and the front portion, said flexible area enabling the front portion to be arranged in a tilted state relative to the rear portion and wherein the seat pan is formed in a single piece.

An arrangement structure for a biological sensor includes a biological sensor of a non-contact type provided in a seat on which a human is seated. The biological sensor detecting biological information of the human with electromagnetic waves. The biological sensor is arranged at a position in the seat avoiding a member that constitutes the seat and interferes with passage of the electromagnetic waves.

To improve the seated feeling of an occupant in a seat having partially different hardness, a vehicle seat includes a seat frame, an S spring which is installed on the seat frame and receives a load of an occupant, and a seat back pad which has a plurality of regions respectively formed of different materials and is disposed between a skin material of the seat and the S spring. The S spring is disposed at a position facing a boundary portion which is provided in the seat back pad and is the plurality of regions respectively formed of different materials.

A support driver for a seat and a support assembly including the same that is using a tube and a structure of a mat that is moved by an inflation and a deflation of the tube. According to an embodiment of the present disclosure, the support driver coupled to a seat frame includes: a support portion coupled to the seat frame; a tube coupled to the support portion; and a mat coupled to the support portion so as to allow the mat to be movable in a direction that is away from the support portion or in a direction that is adjacent to the support portion, with the tube being provided therebetween, in which the tube is configured to push the mat by being inflated according to an operation of a pump that is connected to the tube by a hose.
