Abstract: A safety system for vehicle may include a restraint surface adjustment mechanism for adjusting at least one of a height or an angle of a restraint surface disposed under a vehicle seat during a collision and/or predicted collision in which the vehicle seat is facing in the direction of travel and/or the direction of the oncoming collision. The seat may comprise a bench seat including a first seating space and a second seating space. A first restraint surface adjustment mechanism may be associated with the first seating space and a second restraint surface adjustment mechanism may be associated with the second seating space. The restraint surface adjustment mechanism may include, for example, an inflatable bladder, a movable plate which rotates about an axis, or other restraint surface adjustment mechanisms that adjust at least one of the height, angle, or physical property (e.g., rigidity) of one or more restraint surfaces.

Abstract: 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.

Abstract: A seat for a vehicle may include a seatback including an intermediate portion including a first portion having a first stiffness and a second portion including a second material different than a first material of the first portion, such that the seatback quickly couples an associated occupant and dissipates as much energy as possible. The intermediate portion may be configured such that as at least a portion of the back of an occupant of the seat pushes against a front surface of the seatback and the seatback is at least partially compressed, a reaction force from the seatback against at least a portion of the back of the occupant increases from a minimal reaction force to a first reaction force corresponding to a first displacement, and thereafter the reaction force decreases to a second reaction force as displacement of the front surface of the seatback further displaces.

Abstract: An occupant protection system for a vehicle may include a seat-back actuator system, including a seat-back actuator configured to move a portion of a seat toward a back of an occupant of the vehicle during a collision in which the occupant is facing opposite a direction of travel of the vehicle. The seat-back actuator system may also include an actuator controller configured to receive a triggering signal indicative of one or more of an actual change in velocity of the vehicle, a predicted change in velocity of the vehicle, a collision, or a predicted collision, and cause the seat-back actuator to move the seat toward the back of the occupant. By moving the seat toward the back of the occupant, a maximum rate of change of velocity of the back of the person may be reduced, reducing the likelihood or severity of injury to the occupant due to the collision.
