A positioning system includes a deflection surface disposed within a seat, configured to support an occupant in the seat, and movable in response to motion of the occupant. The positioning system also includes a lock movable between an unlocked position in which the lock permits motion of the deflection surface relative to motion of the occupant and a locked position in which the lock restrains motion of the deflection surface relative to motion of the occupant. The lock is configured to move from the unlocked position to the locked position in response to receiving a signal from a controller, the signal including information indicative of a vehicle event.

A vehicle seat has a lower seat part and a seat backrest. The seat backrest has a backrest structure, a central backrest section which has at least one backrest cushion and a backrest cover, and a left and a right backrest side wall. The seat backrest is provided with at least one expansion element which has at least one cavity that is enclosed by a membrane and can be filled with an expansion fluid from a fluid source. At least one respective fillable cavity of the at least one expansion element is integrated into the backrest cushion of the central backrest section or is provided between the backrest structure and the backrest cushion of the central backrest section to the left and the right of the backrest longitudinal central plane at a lateral distance thereto.

An occupant protection apparatus includes a driver. The driver includes a drive unit, a support shaft, a movable seat pan supported by the support shaft such that the movable seat pan is inclinable in a front-rear direction, a guide groove, a movement pin that is movable along the guide groove, a link that couples the movable seat pan to the movement pin, and an energy absorber. The guide groove includes a first guide groove portion in which the movement pin moves when the movable seat pan is inclined rearward and a second guide groove portion in which the movement pin moves when the movable seat pan is inclined forward. The energy absorber is configured to absorb at least part of a forward load from an occupant when the movement pin moves in the second guide groove portion.

The present disclosure relates to a vehicle seat that includes a seat cushion which is substantially horizontal with respect to a floor of a vehicle. The vehicle seat further includes a seat back including a proximal end and a distal end separated by a longitudinal length, such that the proximal end is pivotably coupled to the seat back. The vehicle seat also includes a track arranged adjacent to the seat cushion and the track has a longitudinal length. The track includes a proximal end and a distal end, such that the proximal end of the track is attached to a biasing element while the distal end of the track is attached to a portion of the seat back. In a crash event, the seat back is displaceable with respect to the seat cushion along the longitudinal length of the track.

Disclosed is a seat rail pair (2) for adjustment of a vehicle seat (8), in particular of a motor vehicle seat, in an adjustment direction (x), comprising a guide rail (10) extending parallel to the adjustment direction (x) for fastening to a vehicle floor, and a fastening rail (21), which is adjustably guided on the guide rail (10) in the adjustment direction (x) for fastening the vehicle seat (8), wherein an energy absorber element (5) is provided in a path, which introduces the force acting on the vehicle seat (8) into the vehicle structure, which energy absorber element permits a movement of the vehicle seat in the adjustment direction (x) under plastic deformation when a predetermined value of the force is exceeded.

The present description relates to an occupant protecting system for a vehicle, a vehicle comprising such an occupant protecting system and an occupant protecting method for such a vehicle. The occupant protecting system comprises a seat assembly, a sensor unit, an actuator unit and a control unit. The sensor unit is configured to generate crash monitoring data of the vehicle. The control unit is configured to determine a crash type based on the crash monitoring data in case of a collision of the vehicle. The actuator unit comprises a pyrotechnic element. The actuator unit is arranged at the seat assembly and capable to adjust a position of the seat assembly. The control unit is configured to cause the actuator unit based on the crash type.

A combination adaptive energy absorption and emergency flotation device for positioning beneath a plurality of seat pans of a seat assembly in an aircraft seating application. The device includes a plurality of fluidly coupled inflatable elastic bladders, at least one constrictor valve fluidly coupling at least two adjacent ones of the plurality of inflatable elastic bladders allowing fluid flow therethrough in response to predetermined pressure on the device from the plurality of seat pans, and a fluid supply source fluidly coupled to the plurality of inflatable elastic bladders for outputting a positive flow of fluid to the plurality of inflatable elastic bladders, wherein the adaptive energy absorption device is detached from the plurality of seat pans to allow removal from beneath the plurality of seat pans for use as an emergency flotation device.

The present invention is an elevated vehicle system. The preferred embodiment of the present invention has a steering wheel, an engine, a plurality of seats, a plurality of windows, and a plurality of wheels. The steering wheel rotates to turn the plurality of wheels. The engine has a transmission and power system. The power system is a battery that provides power to various components within the present invention. The plurality of seats has a seatbelt, a hydraulic lift, and a plurality of buttons. The seatbelt is a flexible, nonelastic material that holds a passenger in their seat. The hydraulic lift is a mechanical system that lifts and lowers the seat. The plurality of buttons is used to control the height positioning of the seat. Additionally, a sensor is used to control the raising and lowering of the seats.

A seat for a vehicle may include a seatback including one or more inflatable bladders that may be configured to deploy in response to a triggering signal indicative of a change of velocity, collision, or predicted collision event. As at least a portion of the back of an occupant of the seat pushes against a front surface of the seatback due to the event, the one or more inflatable bladders compress at least partially the comfortable foam or comfort material in the seatback and expedite engagement of the energy absorbing material.

Embodiments disclose a vehicle including: a magnet unit disposed under a seat and on which a plurality of magnets are disposed; an electromagnetic unit disposed on a floor of a vehicle compartment and including a plurality of electromagnets; and a control unit configured to control the electromagnetic unit, wherein the control unit moves the seat to a preset position on the electromagnetic unit by controlling current applied to each of the electromagnets. Accordingly, the vehicle can improve the degree of freedom in design in a vehicle compartment while providing a passenger's convenience by implementing a seat movement mechanism suitable for the era of autonomous traveling.
