Belt lock for a safety belt
First Claim
1. A safety belt lock having a lock housing forming an insertion path for a cooperating insertion tongue movable along said insertion path in opposite insertion and withdrawal directions, and a locking bar movable into said insertion path for engaging said insertion tongue, said lock housing being surrounded by a shell and having an insertion opening aligned with said insertion path, said insertion opening being at least partially defined by a flange which partially extends into said insertion path when said insertion tongue is not inserted, and which resiliently bears on said insertion tongue when said insertion tongue is inserted into said insertion opening, and said flange when resiliently bearing on said insertion tongue applying to said insertion tongue a clamping force component in said withdrawal direction and a clamping force component perpendicular to said insertion direction.

Abstract
A safety belt lock has a lock housing with an insertion path for an insertion tongue of a safety belt. The insertion opening of the insertion path is defined between opposed resilient flange members bearing on surface portions of the insertion tongue to generate mutually perpendicular clamping forces whereby any rattling noises are avoided.

- 1. A safety belt lock having a lock housing forming an insertion path for a cooperating insertion tongue movable along said insertion path in opposite insertion and withdrawal directions, and a locking bar movable into said insertion path for engaging said insertion tongue, said lock housing being surrounded by a shell and having an insertion opening aligned with said insertion path, said insertion opening being at least partially defined by a flange which partially extends into said insertion path when said insertion tongue is not inserted, and which resiliently bears on said insertion tongue when said insertion tongue is inserted into said insertion opening, and said flange when resiliently bearing on said insertion tongue applying to said insertion tongue a clamping force component in said withdrawal direction and a clamping force component perpendicular to said insertion direction.
- 7. A buckle and tongue assembly for use with a safety belt, said buckle and tongue assembly comprising a buckle, a tongue having a leading end portion which is insertable into said buckle and a trailing end portion which is spaced from said buckle when said tongue is inserted into said buckle, said buckle including latch means for engaging the leading end portion of said tongue when said tongue is inserted into said buckle to block withdrawal of said tongue from said buckle, and rattle preventing means for holding said tongue against sidewise movement relative to said buckle when said tongue is inserted into said buckle, said rattle preventing means including means for applying force to said tongue in a direction transverse to the direction of insertion of said tongue into said buckle at a location between the location where said latch means engages said tongue and the trailing end portion of said tongue.
- 11. A buckle and tongue assembly for use with a safety belt, said buckle and tongue assembly comprising a buckle, a tongue insertable into said buckle, said tongue including a base and a jacket which at least partially covers said base, said buckle including latch means for engaging said base of said tongue to block withdrawal of said tongue from said buckle, and rattle preventing means for holding said tongue against sidewise movement relative to said buckle, said rattle preventing means including means for applying against said jacket a force having a first component extending generally parallel to the direction of insertion of said tongue into said buckle and a second force component extending transversely to the direction of insertion of said tongue into said buckle.
