Abstract: Lock for safety belts with a belt lock and an insertion tab which can be detented at a latch, which latch can be moved transversely to the insertion direction when the insertion tab is inserted, preferably by the latter itself into the open position against a spring force. The latch can be brought out of detent engagement with the insertion tab by a manual pressure member. A run-up bevel is provided at the abutting edges of the latch and the insertion tab. The latch can be moved into the unlatched position only in part by the pressure member and ultimately by the insertion tab itself. The run-up bevel is at the abutting edge of the insertion tab cooperating with the latch with the height of the contact area for the latch smaller than the thickness of the insertion tab.

Abstract: A sling swivel for removably attaching a sling of flat webbing or other strap material to a rifle or other firearm includes a loop member for receiving the webbing. The loop has a neck extending away from one side. A pivotable shaft carrying a movable link member extends through the neck and is spring-biased to urge the movable link toward the neck. A mounting pin is mounted on one end of the movable link member and is slidably receivable in a hole associated with the neck or a fixed link member. Moving the movable link from its normal position allows the mounting pin to be placed through an eye on a rifle, to attach the swivel to the rifle. The spring-biased pivotable shaft mounting pin is received within the hole. A stop extending from the neck, alongside the movable link, protects the movable link against being pushed away from the neck by an eye of a rifle on which the swivel may be mounted.

Abstract: An improved buckle for a child's safety car seat in which a release plate normally bears against a center plate, within an enclosing housing, to receive in locking relation hasp tips having opening cooperating with bosses on the release plate. The housing is configured to avoid cocking or blocking of the hasp tips on insertion, and to bias the housing covering the bail portion of the buckle against peeling away to expose the metal to the harness straps connecting the buckle to the child's car seat.

Abstract: A buckle for receiving a tongue. A pair of helical springs are positioned between the latch and a main body having first slots for receiving one edge of a reinforcement plate which is pivoted downward depressing the latch springs and snapping into place into a yieldable hook shaped portion. A push button is positioned between the reinforcement plate and the cover which has a plurality of downwardly extending hook shaped fingers engaging the plate which secures the cover and main body together.
