An embodiment rear vehicle body structure of a vehicle including an underbody and an upper body coupled to the underbody includes a reinforcing member coupled to an upper surface of a rear floor panel provided on the rear side of the upper body and connected to both chassis frames of the underbody through the rear floor panel.

A passenger□s weight measurement device for a vehicle seat includes an upper rail provided on a lower rail that is fixable to a vehicle floor, the upper rail being movable in at least one of rear and front directions; a load sensor fixed onto the upper rail; and a frame provided on the load sensor and below the vehicle seat. In plan view, the load sensor protrudes from the frame in at least one of left and right directions.

A storage system for a vehicle includes a storage bin. The storage bin is positioned vehicle-downward of the seating assembly of said vehicle. A trim component overlies a door sill of said vehicle. The trim component and the storage bin together define an under-seat storage cavity. The trim component defines a side receptacle distinct from the under-seat storage cavity.

Provided is a conveyance seat capable of appropriately controlling the behavior of the pelvis (lumbar) of a seated occupant when an impact occurs, and thereby suppressing the generation of a compressive load on the spine of the seated occupant. This conveyance seat is provided with a seat cushion. The seat cushion has: a seat cushion frame; a cushion pad placed on the seat cushion frame; and a high-hardness portion provided below the cushion pad and higher in hardness than the material of the cushion pad. The high-hardness portion is disposed such that at least a part of the high-hardness portion overlaps a sinking suppression member in the vertical direction of the conveyance seat. The sinking suppression member is provided in the seat cushion frame or a vehicle body so that sinking of a seated occupant is suppressed. The sinking suppression member is disposed below the high-hardness portion.

An anti-submarine arrangement for a vehicle seat includes an elongated member pivotably attached between opposing members of a seat bottom support structure. A leg is fixedly attached to the elongated member and pivotably attached to a structural portion of the vehicle seat. The elongated member is rotatable forward and downward relative to the structural portion of the vehicle seat. A damper arrangement is attached to the leg and to the structural portion of the vehicle seat. The damper arrangement opposes a forward and downward rotation of the elongated member.

A storage system for a vehicle includes a storage bin. The storage bin is positioned vehicle-downward of the seating assembly of said vehicle. A trim component overlies a door sill of said vehicle. The trim component and the storage bin together define an under-seat storage cavity. The trim component defines a side receptacle distinct from the under-seat storage cavity.

A support element of a vehicle seat includes a body formed by a flexible supporting element and a rigid reinforcing element, with the flexible supporting element defining a cavity extending into a part of the body, the rigid reinforcing element extending into the cavity and being formed by a material that is stiffer than the flexible supporting element and having an affinity with the flexible supporting element. The body is further formed of at least one reinforcing ply extending against at least a part of the rigid reinforcing element.

Provided is a conveyance seat capable of appropriately controlling the behavior of the pelvis (lumbar) of a seated occupant when an impact occurs, and thereby suppressing the generation of a compressive load on the spine of the seated occupant. This conveyance seat is provided with a seat cushion. The seat cushion has: a seat cushion frame; a cushion pad placed on the seat cushion frame; and a high-hardness portion provided below the cushion pad and higher in hardness than the material of the cushion pad. The high-hardness portion is disposed such that at least a part of the high-hardness portion overlaps a sinking suppression member in the vertical direction of the conveyance seat. The sinking suppression member is provided in the seat cushion frame or a vehicle body so that sinking of a seated occupant is suppressed. The sinking suppression member is disposed below the high-hardness portion.

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.

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.
