Problems solved by technology

[0003] A disadvantage of the known seat belt buckle is that the separate arrangement of the linearly moving inertial mass, together with its associated guide rail and strut in the housing of the seat belt buckle, has a relatively large space requirement, so that the buckle body has to be designed accordingly for the larger
In addition, known solutions imply increased costs for production and assembly

Embodiment Construction

[0011] EP 0212507B1 describes the complete structure of a seat belt buckle and its basic individual parts provided in detail, as well as the functional sequence for proper insertion of a seat belt buckle according to this kind, so the disclosure of EP 0212507B1 can also be used for understanding the present invention; thus, we expressly refer to the disclosure cited above.

[0012] As can be seen from the drawing, the sliding buckle 11 slides on the housing 10 of the seat belt buckle, not shown in detail, the sliding buckle is shown in its initial position. The slide buckle can be inserted into the housing 10 in the direction of the arrow 20 .

[0013] At the same time, the inertial block 12 is set to slide along the linear guide rail 13 arranged on the sliding buckle 11 , and the inertial block 12 is installed on the sliding buckle 11 through the linear guide rail 13 . Because the inertial mass 12 must be able to slide relative to the housing 10, as it must also be stated, t...

Abstract

The invention relates to a safety belt buckle for receiving and locking an insertable tongue. Said buckle comprises a housing, a lock locking the insertable tongue and a slide button acting upon the lock, an inertia mass being provided for shock absorption of the safety belt buckle. The invention is characterized in that the inertia mass (12) is held and guided on the slide button (11) and / or the housing and the slide button (11) has a projection (15) that is spaced apart from its guide (13) for the inertia mass (12) and is opposite the bearing axis (17) of the transmission lever (16), said axis being fixed to the housing. The transmission lever (16) acts with its two arms (18, 19) directly on the inertia mass (12) and the projection (15) of the slide button (11).

Description

technical field [0001] The present invention relates to a seat belt buckle for receiving and locking a plug-in tongue, said seat belt buckle comprising a housing providing an insertion path for the plug-in tongue, said insertion path comprising a spring-type ejector, said seat belt buckle also includes a screw and a slide buckle, said screw being mounted in the buckle and cooperating with the groove of the tongue in the locked position, whereupon the screw secures the plug-in tongue in the housing, The sliding buckle slides in the housing and acts on the screw to release the locking, wherein an inertia mass that moves relative to the sliding buckle in the direction of movement of the sliding buckle can be connected to the Slide the buckle to shockproof the seat belt buckle. Background technique [0002] A seat belt buckle of the above character is described in EP 0212507B1. In seat belt buckles of this type, it is necessary to design them to be shockproof, for example, as ...
