A seat belt buckle having a laminated construction. A main body has a cavity in which a double leaf spring is positioned. A latch plate located in the cavity has a pair of outwardly extending arms slidably mounted in a pair of mutually-opposed upright channels mounted in the cavity. The leaf spring abuts the bottom surface of the latch plate forcing the latch plate upwardly to releasably lock in place a seat belt tongue extending through inlet means into the cavity atop the latch plate. A push button is mounted between the main body and a cover fixedly secured to the main body. The push button has outwardly extending legs slidably received in the channels and abutting the arms on the latch plate whereby the push button may be depressed to move the latch plate and leaf or coil spring downwardly releasing the tongue from the buckle. A first reinforcing plate is mounted in a recess on the main body whereas a second reinforcing plate is mounted in a recess within the cover. Fastening means secure together and extend through the cover, the main body and the reinforcing plates. Lateral force exerted on the latch plate by the tongue is transferred to the channels and thus to the reinforcing plates, cover and main body.
In a laminated seat belt buckle comprising a main body member having a cavity therein and a cover member adapted to overlie said body member also having a cavity therein registering with the body cavity, movable latching means for engaging a seat belt tongue and manual operating means accessible at the exterior of the cover member for actuating said latching means, the improvement wherein the the line of junction of said body member and cover member lies in a single flat plane except for opposed offset portions at adjacent ends of the members forming an entry passage for a seat belt tongue into said body member cavity, a first reinforcing plate recessed in the marginal area of said body member and a second reinforcing plate recessed in the marginal area of said cover, said reinforcing plates being contiguous along the line of junction of the body and cover members and generally coextensive with said members, the end portion of said first plate being offset adjacent said entry passage to accommodate entry of a seat belt tongue into said body member cavity, and registering apertures in said plates accommodating said latching means and said operating means.
