A ratcheting belt system with opposed rollers and quick release capability provides two opposed rollers which frictionally allow a tightening belt of a safety harness, cargo securement system, between themselves compressively, via a manually operated ratcheting handle such that the excess length of belt distal to the active portion used for securement is passed through the system substantially parallel to the active portion of belt, and need not be contained on a spool. A ratchet mechanism prevents back-out of the belt through the buckle, a manually operated lever provides for opening of the rollers away from each other and easy, quick exit of the driver, passenger, or cargo from securement.

A seat belt restraint system locking tongue (10) having a locking member (30) which moves to a locked position to clamp a webbing (3) inserted in a shoulder-side webbing insertion slot (12) to restrict movement of the webbing (3). A tongue body (11) includes a restricting portion (25) near the shoulder-side webbing insertion slot (12) to clamp the webbing (3) with the locking member (30) when the locking member (3) moves to the locked position. The length in the longitudinal direction of the webbing insertion slot (12), of a portion of the restricting portion (25) that contacts the webbing (3) to clamp the webbing (3) is smaller than the width of the webbing (3). The locking tongue prevents fraying of the webbing (3) and improves the clamping performance in the event of a vehicle crash.

A seat belt extender comprises a rotatable member having multiple blades of different sizes that engage the receptacle mounted to the vehicle. At the opposite end of the seat belt extender is a receptacle that receives the blade that is connected to the seat belt and/or seat belt and shoulder harness.

A latch plate is selectively latched to, and selectively unlatched from, a buckle. An extender is moved by the latch plate to a retracted position when the latch plate is latched to the buckle and moves to an extended position when the latch plate is unlatched from the buckle.

A ratcheting mechanism composed of a housing that encloses a plurality of pins acting as pawls, engaging with a rack having teeth, wherein each of the pins acts independently, allowing for fine adjustments of the rack. An actuator enables seamless engagement and disengagement of the pins in relation to the rack. A sensor may be used to determine the location of at least one pin within the housing as it is related to the rack.

A rotary lap belt energy attenuator for reducing inertial loads on seat components. In embodiments, a shackle assembly includes a seat frame component, a shackle pivotally attached to the seat component and attachable to a lap belt component, a deformable link attached to the shackle and the seat component, an attachment guide configured to travel along the guideway, and an energy attenuator positioned in the guideway. In use, each of the deformable link and the energy attenuator undergo plastic deformation during rotary motion of the shackle to attenuate impact energy.
