Seat belt buckle
First Claim
1. A seat belt buckle comprising a frame wherein an insertion channel for an insert tongue is formed, a pawl movable in said frame transverse to said insertion channel between a latching position and a release position, a release button slidably guided on said frame in a direction parallel to said insertion channel, said release button, when depressed, engaging said pawl and moving said pawl to the release position, and a catch slidably guided in a direction parallel to said insertion channel between a blocking position and a retracted position, said catch being biased by a spring to the retracted position and movable into said blocking position by inertia when the buckle is exposed to a predetermined acceleration in a direction in which the release button moves upon depression, and said catch, when in said blocking position, engaging the pawl and blocking the pawl in the latching position.

Abstract
A seat belt buckle based on the proven latching pawl design is equipped with simple measures to render it tensioner compatible. The latching pawl is locked in its latching position by a pin-type catch which is preloaded by a compression spring to a retracted position, but shifted into a blocking position in response to high acceleration of the buckle in which it protrudes into the guiding channel of the latching pawl.
