A tongue ( 200, 400 ) for an inflatable belt restraint system, the tongue comprising: a narrow cylindrical hollow tube ( 204 a, 204 b ) comprising a first formed member and a second formed member joined together along respective mating edges of the first and second formed members and two mating portions ( 202 a and 202 b ) forming the looped portion of the tongue.
1. A tongue for an inflatable belt restraint system, the tongue comprising:
a loop to receive a portion of the belt, wherein the loop is formed of a mating first loop part and a second mating loop part, each loop part extending from a respective portion of one of the first or second formed members; wherein the first loop part is integrally formed with the first formed member and the second loop part is formed as an integral part of the second formed member;
wherein each of the first loop part has a first projection with a first projection facing surface and a second projection with a second projection facing surface and wherein and the second loop part has a third projection with a third projection facing surface and a fourth projection with a fourth projection facing surface, wherein the first and third projection facing surfaces are spaced from one another and face each other and the second and fourth projection facing surfaces are spaced from one another and face each other; and
wherein the tongue includes a connecting member which extends between the first and third projection facing surfaces and the second the forth projection facing surfaces.
2. The tongue according to claim 1 wherein the first and third projections are configured as part of a hinge and wherein the connecting member is rotatable therebetween.
3. The tongue according to claim 2 wherein the second and fourth projections are configured to receive an end portion of the connecting member which is opposite the hinge and wherein the end portion of the connecting member is fixedly connected to the second and fourth projections.
4. The tongue according to claim 1 wherein each of the first and second formed member is one of a metal stamping or a polymer, each of the first and second formed member having a back and narrow upraised sides, each side having one of the mating edges.
5. The tongue according to claim 4 wherein the mating edges are joined together by one of braising or welding.
6. The tongue according to claim 1 wherein each of the first loop part and the second loop part have facing surfaces and wherein each facing surface is configured to mate with each other and wherein the first and second loop parts are joined together along an adjacent edge.
7. A tongue for an inflatable belt restraint system, the tongue comprising:
a loop to receive a portion of the belt, the loop formed of two mating parts, wherein the loop is formed of a mating first loop part and a second mating loop part, each loop part extending from a respective portion of one of the first or second formed members;
wherein the mating first loop part is formed integrally with the first formed member and extends away from each of the upraised sides, wherein a first latch opening is located in the first formed member proximate one of an upraised side and a second latch opening proximate an opposite upraised side, and
wherein the mating second loop part is formed integrally with the second formed member and extends away from each of the upraised sides of the second formed member, wherein a third latch opening is located in the second formed member proximate one of an upraised side and a fourth latch opening proximate an opposite upraised side; and,
wherein when the first and second formed members are aligned one to the other, each of the first and third and second and fourth latch openings are also aligned.
8. A tongue for an inflatable belt restraint system, the tongue comprising:
a narrow cylindrical hollow tube comprising a first formed member and a second formed member joined together along respective mating edges of the first and second formed members and including a loop to receive a portion of the belt, the loop formed of two mating parts; wherein the loop is articulated and movable from a locked position to an articulated portion.
9. The tongue according to claim 8 including a secondary member to receive a belt portion.
10. The tongue according to claim 9 wherein the secondary member is attached to the loop.
11. The tongue according to claim 10 wherein the secondary member is another loop.
