Abstract
Web retractors and associated systems and methods for retracting a web, such as a seat belt web, are disclosed herein. In some embodiments, a sealed web retractor includes a frame having a side wall with a first opening, a locking assembly housing attached to the side wall and having a second opening adjacent to the first opening, and a spool shaft having a portion that extends through the first and second openings. In some embodiments, the retractor can further include a bushing and a seal operably disposed in the first opening and extending around an outer periphery of the spool shaft.
Claims20
A web retractor, comprising:
- a frame having a first side wall and a second side wall, wherein the first side wall includes a first opening formed therein, and wherein the second side wall includes a second opening formed therein;
- a spool shaft extending through the first opening and the second opening, wherein the spool shaft is rotatable relative to the frame;
- a locking assembly housing coupled to the first side wall and defining a cavity;
- a locking assembly positioned within the cavity, wherein the locking assembly is operably coupled to the spool shaft and configured to selectively lock rotation of the spool shaft;
- and
- a seal radially positioned between the spool shaft and the first side wall within the first opening, wherein the seal contacts the spool shaft.
A web retractor, comprising:
- a frame having a first side wall and a second side wall, wherein the first side wall includes a first opening formed therein, and wherein the second side wall includes a second opening formed therein;
- a spool shaft extending through the first opening and the second opening, wherein the spool shaft is rotatable relative to the frame;
- a locking assembly housing coupled to the first side wall and defining a cavity, wherein the locking assembly housing includes a base wall positioned against the first side wall;
- a locking assembly positioned within the cavity, wherein the locking assembly is operably coupled to the spool shaft and configured to selectively lock rotation of the spool shaft;
- and
- a seal radially positioned between the spool shaft and the first side wall within the first opening, wherein the seal is spaced apart from the base wall by a gap therebetween, and wherein the seal contacts the spool shaft.
A web retractor, comprising:
- a frame having a first side wall and a second side wall, wherein the first side wall includes a first opening formed therein, and wherein the second side wall includes a second opening formed therein;
- a spool shaft extending through the first opening and the second opening, wherein the spool shaft is rotatable relative to the frame about a longitudinal axis;
- a locking assembly housing coupled to the first side wall and defining a cavity, wherein the locking assembly housing includes a base wall positioned against the first side wall;
- a locking assembly positioned within the cavity, wherein the locking assembly is operably coupled to the spool shaft and configured to selectively lock rotation of the spool shaft;
- a seal radially positioned between the spool shaft and the first side wall within the first opening;
- and
- a bushing radially positioned between the spool shaft and the first side wall within the first opening, wherein the bushing is spaced apart from the base wall by a gap therebetween, and wherein the bushing is positioned side-by-side with the seal along the longitudinal axis.
