The backrest further comprises a seat belt anchoring means support frame, comprising two upper tubes, each extending through a separate through-hole formed in the upper crossmember, so as to extend, at least partially, above the upper crossmember, a lower tube, positioned near the lower crossmember of the backrest frame, and fixed to at least one lateral flank of the backrest frame, at least one connecting tube connecting at least one upper tube to the lower tube.

An occupant restraint system for a vehicle seat operatively mounted in a motor vehicle may include a restraint web operatively coupled to at least one of the vehicle seat and the motor vehicle, an elongated sleeve received on and at least partially about the restraint web, and a sleeve position adjuster coupled to the sleeve and including an actuator normally engaging a portion of the restraint web to fix a position of the sleeve relative to the restraint web and responsive to actuation thereof to disengage from the restraint web to allow the sleeve to be moved along the restraint web.

A latch device includes a latch engageable with a rod portion of a striker, and is capable of transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion, and includes a first shaft member that supports the latch in a manner that permits the latch to rotate, and a base member that supports the first shaft member. The base member is a unitary member which includes a first support wall disposed on one side of the latch and configured to support one end of the first shaft member, a second support disposed on an other side of the latch and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall.

An example embodiment of a system and methods for detecting and reporting whether passengers are seated and secured in their seats within a vehicle may include a passenger sensor configured to provide an output indicative of a presence of a passenger in a seat in a vehicle, a restraint sensor configured to provide an output indicative of a status of a passenger safety restraint associated with the seat, a transmitter configured to be in electronic communication with the passenger sensor and the restraint sensor and to wirelessly transmit data indicative of the presence of a passenger in the seat and the status of the restrain, and a reporting module configured to be disposed proximate a driver of the vehicle. The reporting module may be configured to receive the data from the transmitter, and output a respective status for each of a plurality of seats.

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.

An occupant protection device, which protects an occupant seated in a seat, includes: a seat belt; a front airbag device provided with a front airbag which is placed in an area of a lap belt and inflates to cover a front of the occupant when operated; and a seat airbag device provided with a seat airbag which is arranged inside a seat portion in the seat and inflates so as to raise at least a front portion side of the seat portion upward. The front airbag causes inflation gas to flow into the inside and inflates so as to protrude forward and upward when operated and a thigh abutment surface abutting on a thigh of the occupant and an upper body restraining surface restraining an upper body of the occupant are arranged on an outer peripheral surface of the front airbag when the inflation is completed.

An impact absorbing device for a vehicle seat includes: a first base member; a second base member; and an impact absorbing member. The first base member rotatably supports the second base member. The impact absorbing member includes: a first fixing portion fixed to the first base member; a second fixing portion fixed to the second base member; and a deformable portion. The deformable portion is provided between the first fixing portion and the second fixing portion, and is configured to be bent by the rotation of the second base member. A distance between the first fixing portion and the second fixing portion in an undeformed state of the deformable portion has a value intermediate in a range of variation of the distance that varies depending on the bending of the deformable portion.

A device for arranging a passenger restraint system in a vehicle to secure a passenger seated in the vehicle, including a support arrangement having a vertical support and a cross strut. When arranged on the vehicle, the vertical support is arranged upright on a vehicle floor. The device includes a fastening element, that when arranged on the vehicle, encompasses a rail of a vehicle chassis, at least laterally and beneath, such that, when the support arrangement is arranged on the vehicle, the fastening element bears against the support arrangement. The support arrangement is held on the vehicle chassis by the fastening element and, when the support arrangement is arranged on the vehicle, the fastening element passes progressively through the vehicle floor, starting from the rail of the vehicle chassis.
