, Description:FIELD
The present disclosure relates to the field of vehicle restraint systems.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Restraint systems are widely used in automobile industry for protecting passengers from injury in the event of an impact or sudden braking. Since the structure of each vehicle model is different, a different mounting arrangement is provided for fastening the components of the restraint system. A conventional restraint system comprises webbing, a tongue, a buckle, and a retractor. The buckle secures and releases the tongue which is attached to the webbing. The buckle is designed to hold the tongue firmly and allow the seat belt to be fastened and unfastened with little force. The body in white (BIW) of each vehicle model is structurally different which provides different seating positions for passenger/drivers. Therefore, a different mounting structure is needed to be provided in the BIW to facilitate the mounting of the buckle of the respective type of restraint system.
Maintaining an inventory of different types of buckles is challenging. Even changing a single bolt causes change of part number for which the supplier charges significantly higher considering new part development. Complete carryover of an existing buckle design is not an easy task due to packaging constraints for the different type and category of vehicles. Further, even a minor modification on the BIW requires huge investment in modifying dies and tooling.
There is, therefore, felt a need of an adjustable restraint system that overcomes the aforementioned drawbacks.

OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
An object of the present disclosure is to provide an adjustable vehicle restraint system.
