A seat belt to increase a force for restraining a passenger's lower body in a sitting state of a relaxation mode while satisfying existing laws in a normal sitting state and to a movement control method thereof includes an anchor unit provided on a lower portion of a first side surface of a seat and configured for allowing webbing of the seat belt to be locked thereto and an anchor moving apparatus configured to move the anchor unit forwards and backwards thereof, and to a movement control method thereof.

The restraint assembly includes a mounting plate having a vertical slot. The plate covers an opening in a surface which is located to restrain a patient. An adapter buckle has a “T” stop which is releasably coupled to the vertical slot. The buckle includes an arm and a head. The head includes a horizontal slot for releasable receipt of a strap of the patient restraint. The arm includes an angular bend which positions the head relative to the plate during use. A lock may be used to prevent undesired separation of the buckle from the plate.

Seatbelt assemblies for motor vehicle occupant restraint providing enhanced frontal impact restraint characteristics. Embodiments illustrated a displacement of the intersection positioned between the lap and shoulder belt portions of an active three-point type belt system. In one set of embodiments particularly useful with dual retractor systems, adaptive positioning provisions allow the point of intersection to initially occur at or near the seatbelt latch plate and when a restraint load occurs components release to allow repositioning of the intersection. In other embodiments best implemented in single retractor systems, a turning loop is provided which displaces the webbing slot separating the lap and shoulder belt sections from the buckle latch plate.

In this buckle device, a base end portion of a belt is folded back on itself to form a ring-shaped portion, and the belt is wound onto a spool in a state in which the ring-shaped portion of the belt has been inserted through an insertion hole in the spool. This enables a winding radius of the belt to be increased by the base end portion of the belt and enables a load at which the belt is permitted to be pulled out to be reduced, when the belt is pulled out from the spool.

In this buckle device, when a second wind of a belt is pulled out from a spool, a load at which the belt is permitted to be pulled out is small, whereas slide resistance of the belt with respect to a slide face is large. When a first wind of the belt is then pulled out from the spool, the belt pull-out permitting load is large, whereas the slide resistance of the belt with respect to the slide face is small. This enables variation in a load at which extending of a buckle body is permitted to be suppressed.

To make a rotatable vehicle seat be rotatable in a small space, in a vehicle seat (1) including a seat cushion (7) provided on a floor (2) of a vehicle and a seat back (8) provided on the seat cushion, the seat cushion is provided on the floor so as to be rotatable about a selected one of multiple rotation axes (A) extending substantially vertically. Preferably, a rotation device (4) is provided between the floor and the seat cushion, the rotation device being configured to enable rotation about the selected one of the multiple rotation axes while restricting rotation about any of the remaining rotation axes.

A vehicle occupant restraint system for a seat of a vehicle. The system includes a first arm portion mountable on a first side of the seat, the first arm having an engaging portion; and a second arm portion mountable on a second side of the seat, the second arm having an engaging portion, the engaging portion of the first arm portion being engageable with the engaging portion of the second arm portion to restrain an occupant on the seat. At least one of the first arm portion and the second arm portion is adjustable relative to the seat.

In a lift-up buckle device, a worm wheel is engaged with a screw drive. When a worm is rotated in a forward direction and causes the screw drive to move downward, the worm moves the worm wheel downward. On the other hand, when the worm is rotated in a reverse direction and causes the screw drive to move upward, the worm moves the worm wheel upward. Consequently, the worm wheel may be stably engaged with the screw drive, and the worm wheel and worm may be stably mated.

An occupant protection device including a seat belt including a shoulder belt and a lap belt, a locking tongue that is detachably joined to a buckle, that allows the seat belt to pass therethrough, and that is capable of switching between an unlock state in which the seat belt is allowed to move with the locking tongue being between the shoulder belt and the lap belt and a lock state in which movement thereof is restricted, a shoulder-belt puller that is capable of pulling the shoulder belt to apply a tensile force thereto, a side-collision detector that detects a side collision or a precursor thereof, and a control unit that changes a state of the locking tongue into the lock state and causes the shoulder-belt puller to pull the shoulder belt when the side-collision detector detects the side collision that occurs opposite an occupant or the precursor thereof.

A restraint system is disclosed for use in vehicle seats that provides enhanced occupant restraint while minimizing belt loading injuries, is intuitive to don and remove, and includes an emergency release feature to allow rapid seat egress by eliminating continuous belt loops. The restraint uses improved belt routing to minimize upper torso rotation, which is critical for vehicles where occupant flail injuries from contact with the vehicle interior are likely. The installed restraint includes a crisscross belt pattern across both the occupant's upper torso and pelvis region, with an alternate configuration which incorporates a single lap belt. The restraint has demonstrated significantly reduced upper torso rotation compared to the current state-of-the-art, 5-point restraint system when exposed to a typical aerospace combined vertical and longitudinal crash pulse yet is as intuitive to don as the typical automotive-style 3-point restraint system.
