Provided is a pre-tensioner for a seat belt, the pre-tensioner including a housing, a carrier disposed on a first surface of the housing, a fixing member connected to the carrier, a first pulley disposed in a first zone of the first surface of the housing, a second pulley disposed in a second zone of the first surface opposite to the first zone with respect to the carrier, a driving unit having at least a portion coupled to the second pulley, and a belt disposed to mesh with the first pulley, the second pulley, and the carrier.

A seat for a motor vehicle includes a basic shell and a seat surface. The seat surface includes a vacuum layer and an air cushion layer; and the air cushion layer is arranged between the vacuum layer and the basic shell. Also disclosed is a motor vehicle having such a seat.

A system for improving safety of an occupant by a vehicle seat belt, which can provide adaptive protection for an occupant in different seat positions and different sitting postures is provided. A method for improving safety of an occupant by a vehicle seat belt is also provided, along with a a computer-readable medium. The a system for improving safety of an occupant by a vehicle seat belt includes an in-vehicle observation system, an active seat belt system, and an integrated safety domain control unit. The integrated safety domain control unit formulates a vehicle seat belt protection strategy based on received data from the in-vehicle observation system, and a slack state of an active retractor and a positional state of an active lift buckle in the active seat belt system, to implement selective tightening or loosening of the active retractor and/or selective lifting or lowering of the active lift buckle.

A vehicle includes a vehicle body having a pillar. The vehicle includes a track supported by the pillar. The vehicle includes a bar supported by the track. The bar is slidable relative to the track from a raised position to a lowered position. The vehicle includes a seatbelt webbing extending over the bar. The vehicle includes a piston supported by the pillar. The piston includes a piston rod connected to the bar and a piston cylinder supported by the pillar. The piston rod and the piston cylinder define a volume filled with a resilient material.

A system includes a base. The system includes a buckle movable from a retracted position away from the base to an extended position. The system includes an actuator supported by the base and operatively coupled to the buckle to move the buckle to the extended position. The system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the actuator to move the buckle to the extended position in response to determining that tension of a seatbelt webbing is above a predetermined threshold and that a vehicle impact has not been detected.

Guidance to a vehicle occupant is directed to manual adjustment of a height of a D-ring mechanism of a safety belt. First data of the occupant is collected which is indicative of a target height for the D-ring mechanism. Second data is collected indicative of a current height of the D-ring mechanism. The target height and the current height are compared to generate an adjustment amount whenever their difference is greater than a predetermined threshold. Visual guidance is presented to the occupant on an HMI display panel wherein the visual guidance describes taking an particular action to achieve the manual height adjustment of the D-ring mechanism. A further visual instruction is presented to the occupant on the HMI display panel wherein the visual instruction identifies the adjustment amount.

A safety belt presentation system includes a safety belt presentation track extending from a first position to a second position spaced from the first position, a latch that includes a tongue disposed between a first side of the latch and second side of the latch and a first coupling portion, and a driving mechanism that includes a second coupling portion configured to releasably couple the first coupling portion of the latch. The driving mechanism is configured to control the latch to move from the first position to the second position along the safety belt presentation track when the first and second coupling portions are coupled.
