ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates generally to seatbelt assemblies, and more particularly to an anti-roping turning loop for a seatbelt which is supported on a pillar or the like of a car body and slidably guides the webbing of a seatbelt in a longitudinal direction.
BACKGROUND AND SUMMARY OF THE INVENTION
A seatbelt unit is provided on a seat of a vehicle to restrain the occupants of a vehicle in an emergency such as a vehicle collision. Some seatbelts are provided with a turning loop, which is supported on a pillar of a car body and slidably guides the webbing of the seatbelt in a longitudinal direction. The turning loop helps to properly orient the seatbelt with respect to the vehicle passenger. If the webbing is twisted, the webbing is not only incorrectly adapted to the occupant, but smooth movement of the webbing is also hindered. Therefore, it is desirable to keep the webbing from becoming twisted. In prior designs which are utilized to prevent twisting of the seatbelt webbing, other problems such as binding or tearing of the lateral portion of the webbing may occur. The object of the present invention is to provide a turning loop for a seatbelt, in which the webbing is not twisted and the binding or tearing of the lateral portion of the webbing can be prevented.
These and other objects of the present invention are obtained by providing a turning loop for a seatbelt which is adapted to be mounted on a car body and which includes a guide portion defining a guide slot for receiving a seatbelt therethrough. The guide slot defines a first surface which is adapted to be slidably engaged by the seatbelt and a second surface disposed opposite to and spaced from the first surface. The guide slot terminates at opposite ends into a loop-shaped escape portion and includes a pair of anti-looping projections extending from opposite ends of the second surface adjacent to the loop-shaped escape portions. A distance between the anti-looping projection and the first surface is less than twice a thickness of a seatbelt.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood however that the detailed description and specific examples, while indicating preferred embodiments of the invention, are intended for purposes of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
