Energy absorbing turning loop cover
View Patent ↗A turning loop cover is disclosed that is configured to slidably engage a turning loop and a fastener of a seatbelt system. The turning loop cover is primarily formed of a housing that has an internal volume and a first surface wherein a plurality of ribs extend from the first surface into the internal volume. The ribs are configured to attenuate a force acting upon the first surface of the housing.
1. A turning loop cover configured to attach to a turning loop fastened to an automobile structural member, the turning loop cover comprising:
a housing having an internal volume, and a first surface;
a plurality of ribs extending from the first surface into the internal volume, the ribs configured to attenuate a force acting upon the housing, the ribs being configured in a pattern comprising a center rib, two turning loop engaging ribs running parallel to the center rib and spaced at a distance on either side of the center rib, two fastener engaging ribs running parallel to the center rib and spaced between the turning loop engaging ribs and the center rib, and two intersecting ribs running perpendicular to the center rib and intersecting the fastener engagement ribs; and
an opening in the side of the housing whereby the turning loop cover can slidably engage the fastened turning loop.
2. The turning loop cover, as recited in claim 1 , wherein the rib configuration is capable of attenuating the force by buckling.
3. The turning loop cover, as recited in claim 1 , wherein the center rib, the fastener engaging ribs, and the intersecting ribs extend from the first surface to a height sufficient to engage the turning loop fastener.
4. The turning loop cover, as recited in claim 1 , wherein the turning loop engaging ribs extend from the first surface to a height sufficient to engage the turning loop.
5. The turning loop cover, as recited in claim 1 , wherein two turning loop engagement ribs and the center rib are ramped at the opening of the housing.
6. The turning loop cover, as recited in claim 1 , wherein the housing compressively engages the turning loop.
7. The turning loop cover, as recited in claim 1 , wherein the head impact criteria is less than 1000.
8. The turning loop cover, as recited in claim 1 , wherein the turning loop cover is generally bell shaped.
9. A turning loop cover capable of engaging a turning loop fastened to an automobile structural member, the turning loop cover comprising:
a housing having an internal volume, a first surface, and a second surface;
a plurality of ribs extending from the first surface of the housing, the ribs configured to attenuate a force acting upon the housing; and
a channel in the second surface of the housing opposite the ribs, the channel defining a plurality of wings, the wings configured to compressively engage the turning loop.
10. The turning loop cover, as recited in claim 9 , wherein the rib configuration is capable of attenuating the force by buckling.
11. The turning loop cover, as recited in claim 9 , wherein the rib configuration is capable of attenuating the force by ripping.
12. The turning loop cover, as recited in claim 9 , wherein the rib configuration is capable of attenuating the force by tearing.
13. The turning loop cover, as recited in claim 9 , wherein at least one wing has a perforation to engage a protrusion on the turning loop.
14. The turning loop cover, as recited in claim 9 , wherein the turning loop has a perforation to engage a protrusion on the wing.
15. The turning loop cover, as recited in claim 9 , wherein the wings are semi-flexible.
16. The turning loop cover, as recited in claim 9 , wherein the wings are capable of engaging the turning loop and fastener in an interference fit.
17. The turning loop cover, as recited in claim 9 , wherein the second surface of the housing is capable of locking to the turning loop fastener to maintain an engagement.
18. The turning loop cover, as recited in claim 9 , wherein the turning loop cover is generally triangular shaped.
19. The turning loop cover, as recited in claim 9 , wherein the turning loop cover is capable of being engaged to the turning loop by a single sliding motion.
20. A turning loop cover configured to engage a turning loop fastened to an automobile structure, the turning loop cover comprising:
a housing having an internal volume, a first surface, and a second surface, wherein the first surface is substantially parallel to the second surface and the first and second surfaces are connected via a partial enclosure wall;
a plurality of ribs extending from the first surface and into the internal volume;
an opening in the housing configured to slidably receive the fastened turning loop; and
a channel in the second surface defining a plurality of wings that are configured to bias the turning loop against at least one of the ribs.
