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 passenger seat comprises a backrest, a seat element and a size increasing mechanism which is configured to convert a weight acting on the seat element when a user sits in the passenger seat into an increase in the depth of a seat pan of the seat element that can be used by the user from a rest-position depth to a to an operational-position depth.

A seat cushion structure capable of adjusting softness and hardness, comprising a cushion sponge (1), a wheel-spoke seat inner housing (2), a seat sponge (3) and a seat outer housing (4), which are sequentially disposed from top to bottom; a coil spring (11) is fixedly provided on the wheel-spoke seat inner housing (2); an adjustment handle (5) is provided outside the seat outer housing (4), an adjustment mechanism is connected to the adjustment handle (5) and provided inside the seat outer housing (4); the adjustment mechanism is also connected to the coil spring (11), configured for adjusting contraction radius of the coil spring (11); the adjustment mechanism is capable of adjusting contraction radius of the coil spring (11) since being controlled by the adjustment handle (5), thereby the softness and hardness of the seat cushion structure is adjusted.

An easy entrance/exit system for a vehicle includes a vehicle seat, a pad, a pad-side magnetic device, and a seat-side magnet. The vehicle seat includes a seat base. The pad is supported atop the seat base for swiveling about a pivot point. The pad-side magnetic device is coupled to the pad at the pivot point. The seat-side magnet is within the seat base at the pivot point. The seat-side magnet is configured to apply a magnetic field to the pad-side magnetic device to govern swiveling of the pad about the pivot point.

A seat device includes a cushion portion configured to elastically support a seated person and a seat frame configured to support the cushion portion. The cushion portion includes a plurality of divided cushions divided in a seat width direction. The plurality of divided cushions each include a seat pad a seat cover that individually covers each seat pad, and a resin member that is engaged with at least one of the seat cover or the seat pad and is thus individually integrated with the seat pad covered by the seat cover. The resin member includes a snap-fit structure fixed to the seat frame by inserting from a seat front side to a seat back side.
