A fixed shoulder-belt and adjusting-belt connection keeps child seat restraint length adjustable while preventing impact deformation.

A curved rail lets the belt buckle and anchor move with seatback recline, maintaining iliac support and reducing submarining risk.

A detachable belt limiter pulls the shoulder belt downward to stop upward slippage and reduce neck and face injuries in child seats.

Magnetic attraction and an elastic member replace multiple reset springs in a child safety buckle, cutting parts, weight, and assembly cost.

A fixed belt connector lets child seat shoulder straps stay adjustable while resisting stretch and deformation during impact.

An actuator moves the seat buckle from the seatback to a deployed position when exit intent is detected, improving buckle access and comfort.

Mounting the side belt on the slide frame lets it move with the seat, reducing abdomen tightening during off-road seat adjustment.

Deformable belt-contact structures in child restraint seats absorb belt energy during crashes, reducing force on occupants while maintaining restraint.

A motor, gears, and lead screw reposition the buckle arm through a 120-degree range for smoother seat belt adjustment and better comfort.

A detachable connecting buckle assembly lets multi-point seat belts adjust height for different body shapes while reducing interference with user movement.

A motorized shuttle raises the lap belt for wheelchair users, reducing manual buckling effort while enabling secure restraint in vehicles.

A clamp-adjustable sleeve and spring-biased restraint web help vehicle seats stay secure in impacts while still allowing seat position changes.

A tension-activated damping seam lets the chest move forward in a controlled way, reducing head acceleration without losing four-point restraint stability.

A stopping body controls axial movement so the worm wheel stays stably mated with the worm, improving buckle motion with less structural complexity.

Electrical heating of a shape memory alloy moves the buckle release button for consistent restraint disengagement with manual override.

A roof-supported deployable strap restraint adds multi-point crash protection while preserving the comfort and convenience of a 3-point seatbelt.

A roll-cage coupler holds safety belts and harnesses upright and separated to prevent tangling, improve access, and avoid interior damage.

Magnetic seat and belt attachments hold child seat harness straps open, avoiding buried buckles and simplifying child placement.

A spring-loaded clamp keeps the seat belt height adjuster at the set position when webbing tension drops, avoiding repeated manual repositioning.

Adjustable restraint element connects to a three-point seat belt and vehicle anchor point to stabilize the head and neck area of sleeping children.

A webbing catcher uses a pivoting adjusting portion to retain seat belt webbing without a plug-in tongue.

A vehicle seat belt through anchor attaches to a headrest or its fixing part to guide the shoulder belt diagonally downward.

Segmented webbing components replace bulky child seats, reducing installation time while maintaining safety.

A seatbelt retention device positions the waist section between legs to redirect restraint force away from the abdomen.

A lift-up buckle device uses flexible wire coupling members to displace the fastener upon impact, absorbing external force through elastic deformation.

A retrofit seat belt system uses a central base plate anchored to the bus floor for structural support.

A seatbelt loop buckle features two lobes formed by local depression to create a fold that acts as a damping element.

Segmented lap and shoulder straps with an extended two-way quarter-turn sure-release receptacle resolve snagging delays on body armor.

A soft-close stowage compartment conceals a vehicle safety belt tongue using a damper-controlled sliding door.

An integrated worm shaft with drive spur wheel teeth reduces axial space and component count in vehicle seat belt feeders.

A vehicle seat integrates retractable shoulder and crotch straps with a multi-point buckle for rapid child restraint deployment.

A lift-up buckle device uses a soft first cover to protect coupling members from guide section contact during displacement.
