Embodiment Construction

[0020] The subject matter of selected embodiments of the present invention is described here with specificity to satisfy statutory requirements. However, the description itself is not intended to limit what is regarded as the invention. Rather, the claims define the invention. The claimed subject matter, along with other present or future technologies, may be embodied in other ways, to include different elements or combinations of elements similar to those described in this document.

[0021] refer to figure 1 , depicts a cross-section of a portion of the seat belt device 10 . The seat belt assembly 10 includes a seat belt webbing 12 that is at least partially wrapped around a main shaft 14 . The spindle 14 includes a spindle body 16 , a first spindle flange 18 , and a second spindle flange 20 . Spindle flanges 18 and 20 block the area in which the seat belt webbing 12 is received. The main shaft 14 includes a protrusion 22 or trunnion connected to a coil spring 24 which ...

Abstract

A device comprising various elements for limiting the load of a seat belt. For example, the device includes a seat belt webbing and a shoulder anchor secured to a portion of the webbing. Buttons are attached to the strap at a distance from the portion secured to the shoulder anchor. When the strap is pulled out, the button can engage the lever to control the energy absorption of the seat belt.

Description

technical field [0001] The present invention relates generally to a seat belt load limiter and, more particularly, to a device for controlling a torsion bar that limits the force of a seat belt webbing unwound from a spindle. Background technique [0002] One countermeasure for occupant protection during a crash of a vehicle is a seat belt restraint system. The force exerted by the seat belt on an occupant's chest or other body part during a crash depends on factors such as vehicle speed and deceleration, and occupant dimensions. Safety technologies associated with seat belts often include pretensioners and load limiting devices to properly manage energy in a timely manner to minimize injury to vehicle occupants. [0003] Seat belt retractors for vehicles often include features to limit the force applied to the seat occupant and to adjust belt tightening. These functions may be adjusted based on various factors such as vehicle speed, occupant dimensions, seating position, ...
