In one embodiment, a vehicle seat includes a seating portion and a seat back extending from the seating portion. The seat back defines a rear facing surface and a recessed area formed in the rear facing surface. The recessed area extends from an upper surface of the seat back toward a central portion of the seat back. The recessed area defines a void between the vehicle seat and a child seat positioned proximate to the seat back.

A seat (1) comprises a seating surface (2) suitable to receive a user and a backrest (3) adaptable according to the user's needs. The seat further comprises a support structure (4) configured to connect the seat to the backrest. The backrest comprises an upper shoulder portion (6) and a lower lumbar portion (7) and the lumbar portion is movable along the support structure while the shoulder portion remains at a fixed height with respect to the support structure (4).

A seatback assembly includes a pair of lateral seatback assembly frame members and a moveable thoracic back support defining a support surface operably coupled with an upper thoracic support bracket. An attachment assembly operably couples the thoracic back support to the upper thoracic support bracket, and includes a pair of mounting lugs disposed on either of one of the upper thoracic support bracket or the moveable thoracic back support, and a pair of mounting bosses disposed on the other of the upper thoracic support bracket or the thoracic back support. The seatback assembly is assembled by aligning the pair of mounting lugs with the pair of mounting bosses as the moveable thoracic back support is horizontally positioned above the lower seatback insert, whereby the pair of mounting lugs are received within the pair of mounting bosses, and vertically lowering the moveable thoracic back support relative the lower seatback insert.

An assembly includes a seat, a lap retractor fixed relative to the seat, a shoulder retractor fixed relative to the seat, and a first buckle fixed relative to the seat. A lap belt is retractably extendable from the lap retractor. A first tongue is fixed to the lap belt and is releasably engageable with the first buckle. A second buckle is fixed to the lap belt. A shoulder belt is retractably extendable from the shoulder retractor. A second tongue is fixed to the shoulder belt and is releasably engageable with the second buckle.

A seat of a vehicle is designed for safety to reduce risk of injury to an occupant of the seat in the event of an abrupt movement or a collision involving the vehicle from the rear. The seat may have seatback geometry designed to promote coupling an occupant to the seat, thereby minimizing a gap between an occupant and the seatback and, therefore, the impact forces to the occupant in a rear-facing collision by reducing a relative velocity between the occupant and the seat, as well as absorbing energy of the occupant over a longer distance. The seat may include one or more materials that plastically deform under a force imparted on the seat by the occupant accelerating relative to and toward the seat during a vehicle collision. Cavities in the seat can be used, in some examples, to create a particular compressibility for optimizing impact.

A vehicle seat for supporting an occupant in a vehicle. The vehicle seat includes a backrest and a headrest.

A seat back (20) includes an upper thoracic support section (20a) for supporting at least a portion corresponding to a lower part of the upper thoracic spine of a seated occupant, and a lower thoracic support section (20b) disposed on a front side with respect to the upper thoracic support section (20a) and configured to support a portion corresponding to the lower thoracic spine of the seated occupant. The lower thoracic support section (20b) is configured to displace backward greatly, as compared with the upper thoracic support section (20a) in such, a way that the upper thoracic spine of the seated occupant is inclined forward, when backward inertia force acts on the seated occupant.

A shape adapting system of a cushion assembly and method of forming a shape adapting system of a cushion assembly include an array of cells that retain a fluid, a fluid exchange sub-system coupled to the cells, wherein the fluid exchange sub-system fluidly connects the cells together, and at least one valve coupled to the fluid exchange sub-system. The valve(s) is configured to move between an open position in which the fluid is able to migrate among the cells to change a shape of the support base, and a closed position in which the shape of the support base is maintained.

The present disclosure relates to a seat that may have a support structure and a pad having a support wire attachable to the support structure. A retainer may be provided which is fixed at one end through an opening in the support structure and at the opposite end onto the support wire. The retainer may have a mounting member to fix through the opening and a hook to catch the support wire, the mounting member having a use position and a mounting position that is inclined relative to the use position. The mounting member and the hook may be joined by a spacer bar.

A vehicle seating arrangement includes a first seat and a first seatback. A side-wing seat extends from the first seat. A surface of the side-wing seat is vertically displaced from a surface of the first seat.
