A seat assembly for a vehicle, in particular a public transport vehicle such as a bus or train, comprises a transversely positioned bench seat in front of which there is a wheelchair space. In front of the transversely positioned bench seat in the travel direction of the vehicle is arranged a barrier device comprising at least one barrier element and a rotation axis, about which the barrier element can be moved between a tilted-down position extending in front of the transversely positioned bench seat and a tilted-up position which leaves the wheelchair space free.

Vehicle seats, vehicles including the vehicle seats, and methods of promoting ease of access to the vehicles are provided. The vehicle seats include a frame coupled to a floor of a vehicle, the vehicle having a front, a rear, and oppositely disposed sides, a seatback coupled to the frame and configured to support a back of an individual while the individual is sitting on the vehicle seat, and a seat cushion coupled to the frame and configured to support the individual while the individual is sitting on the vehicle seat. The seat cushion includes a front portion movably coupled to the frame and a rear portion disposed in a fixed position between the front portion and the seatback. The front portion is configured to selectively move from a driving position to a boarding position by moving the front portion on the frame toward a first side of the vehicle.

A frame for a vehicle seat is provided, in particular for a vehicle seat for people with a disability. The frame is made of aluminum or an aluminum alloy. A substructure for receiving the frame is also provided, in particular for reversibly releasably coupling to a vehicle structure, with the substructure being made at least partially or completely of aluminum or an aluminum alloy.

A vehicle seat configured to be fixed in a vehicle is defined. The vehicle seat comprises a seat back configured such that when the seat is fixed in the vehicle there is a gap between a lower edge of the seat back and a floor of the vehicle to enable wheels of a wheelchair to protrude through the gap. The vehicle seat further comprises a seat base wherein the seat base is either: foldable between a first position in which the seat base acts as a base to the seat and a second position in which the seat base is stowed against the seat back; or removable from the seat back. The seat base is foldable or removable to allow the seat base to be stowed when the seat is used by the wheelchair.
