Provided is a conveyance seat in which an increase in size is suppressed while an impact to be applied to a seated occupant when an impact such as a collision is generated is properly absorbed. A vehicle seat includes a seat cushion. The seat cushion includes a seat cushion frame including a pair of side frames provided to be separated from each other in a width direction of the vehicle seat, a seat cushion pad placed on the seat cushion frame, and an impact absorbing member provided below the seat cushion pad. The impact absorbing member is disposed between the pair of side frames in the width direction of the vehicle seat. The impact absorbing member is provided with a cavity portion. The impact absorbing member is supported from below by a plate-shaped member.

Provided is a core material of a seat cushion for a vehicle, including: a thermoplastic resin expanded beads molded article having a substantially rectangular shape in top view, that has thick portions on a front side and both sides of a circumferential portion thereof, and that has an occupant seating portion on an upper surface in an inner region thereof; and an annular frame member that is insert-molded at the circumferential portion of the thermoplastic resin expanded beads molded article. In the thermoplastic resin expanded beads molded article, formed are first slits having: slit pieces that extend along a front frame member at a position in front of the occupant sitting part and inside from the front frame part; and slit pieces that extend along a side frame member at a position outside from the occupant sitting part and inside from a side frame part.

Structures of seating systems for human users are disclosed. In one embodiment, the structure comprises: a frame; a seat structure supported by the frame; and a back rest structure supported by the frame. The seat structure comprises a thigh support region and a pelvic support region where the pelvic support region defines a pelvic well for receiving an ischial tuberosity of the user and also provides a fulcrum to assist in rotating the pelvis of the user. The back rest structure comprises a gluteal panel for supporting a gluteal mass of the user and a posterior superior iliac spine (PSIS) panel disposed above the gluteal panel. The PSIS panel is adjustable to cause movement of a PSIS of the user and cooperate with the pelvic well to cause rotation of the pelvis of the user about the fulcrum provided by the pelvic well.

A vehicle seat (1) includes a seat cushion (2) and a seat back (3), in which the seat cushion (2) is given a stiffness distribution in a front-rear direction in such a way that a front part of the seat cushion is provided with a low stiffness region (PSc) which is more flexible than a rear part of the seat cushion being a high stiffness region (PHc).

A vehicle includes a cabin and a passenger seat assembly located in the cabin. The passenger seat assembly includes a base support assembly mounted to a floor of the cabin and comprising walls that form a storage compartment. A seat is supported by the base support assembly. The seat includes a seat back frame that supports one or more cushions thereon. A seat base frame supports one or more cushions thereon forming a seat base. The seat base frame is formed as a monolithic, single piece structure from a plastic resin material. The seat base frame has a sitting portion and a raised portion located forward of the sitting portion. The raised portion increases in elevation above the sitting portion to an apex of increased distance from the floor.

A passenger protection apparatus includes a seat, an activation member, a first detector, a second detector, and a controller. The seat has a seat cushion on which a passenger can sit. The activation member is configured to be activated upward in the seat cushion. The first detector is configured to detect or predict a collision of a vehicle. The second detector is configured to detect a sitting state of the passenger sitting on the seat cushion. The controller is configured to control activation of the activation member. The activation member can change an activation point at which the activation member is activated upward. When the first detector detects or predicts a collision of the vehicle, the controller sets the activation point on a basis of the sitting position detected by the second detector, and activates the activation member upward in the seat cushion at the determined activation point.

An anti-submarining seat cushion for a vehicle includes a main body constructed of an anisotropic material. The anisotropic material includes a primary material including a primary stiffness and a plurality of inserts that are dispersed throughout the primary material. The plurality of inserts exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, where the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.

A vehicle seating apparatus includes a structural tub and a protective seat load floor wherein the protective seat load floor includes an anti-submarining feature. The apparatus can also be disposed on top of the structural tub housing a battery for an electrified vehicle, wherein the seat load floor serves as the battery cover.

A vehicle seat belt device includes: an anchor part configured to be provided at a vehicle seat or a vehicle body on a first side in a width direction of the vehicle seat, and to displace a lower end portion of a buckle device to a vehicle front side by being deformed by a load applied from a lap belt to the buckle device at a time of vehicle collision; and a buckle rotation mechanism configured to include a guide part that is provided at the vehicle seat or body on a vehicle downward side of the buckle device and inclined downward toward the vehicle front side, and a pull-in part that connects the guide part and an upper portion of the buckle device and is slidable along the guide part, and to rotate the buckle device to the vehicle front side and downward side due to the displacement.

A seating assembly comprises a lower seating assembly having a lower surface displaced above a floor pan, a mounting bracket operably coupling a forward edge of the lower seating assembly to the floor pan, and a storage bin comprising a horizontally disposed frame member disposed between the lower surface and the floor pan, wherein the storage bin, the floor pan, and the lower surface define an enclosure below the lower seating assembly.
