Benefits of technology

[0005]A seat belt buckle according to the present invention has at least one damping device provided on the spring. Such a damping device may influence the noise generated by the seat belt buckle in two ways. It can effectively reduce the releasing speed of a spring, without affecting the spring load. By reducing the releasing speed of the springs, less acoustic noise is created during opening and closing of the seat belt buckle according to the invention. Through the selection of the damping material, which may have sound-absorbing properties, the developed sound may alternatively or additionally be absorbed and the developed noise may be further reduced.

Problems solved by technology

Such a damping device may influence the noise generated by the seat belt buckle in two ways.

Embodiment Construction

[0014]The terms “up”, “down”, “left” and “right” used in the description of the examples relate to the figures in an orientation with normal legible reference numerals and figure descriptions.

[0015]In the embodiment of the prior art seat belt buckle 65 according to DE 199 04 567 C1 shown in FIG. 2, the components of which are shown in the exploded view of FIG. 1, a locking frame comprises an upper plate 1 and a lower plate 2. The two plates 1, 2 are connected to one another by connecting pins 26. Between the upper plate 1 and the lower plate 2 a guide channel 3 is formed. In the guide channel 3 an ejector 5 is guided such that it can be displaced in a longitudinal direction. The ejector 5 is pretensioned in an ejecting direction of a buckle tongue 4 by an ejector spring 6, which is supported on a stop 22 fixed to the locking frame 1, 2. The buckle tongue 4 is connected in a common manner to a seat belt, which is not shown in detail. To lock the seat belt with the seat belt buckle, t...

Abstract

A seat belt buckle has a frame that forms an insertion path for a buckle tongue of a seat belt. The seat belt buckle includes a locking device having a locking member for locking the buckle tongue) in the locked state. A retaining member is tensioned by a spring for securing the locking member in a locked state. An ejector for the buckle tongue is tensioned by a spring that is provided with at least one damping device to reduce the noise generated when the seat belt buckle changes from a locking state to a released state.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a seat belt buckle.BACKGROUND OF THE INVENTION[0002]A seat belt buckle has a frame, which forms an insertion path for a buckle tongue of a seat belt, further having a locking device with a locking member for locking the buckle tongue in a locked state in a releasable manner, a retaining member tensioned by a spring for securing the locking member in the locked state, an ejector for the buckle tongue, with spring tension being applied to the ejector, and a push button for actuation of the locking device. A seat belt buckle of the type described above is known from DE 199 04 567 C1 for example.[0003]Known seat belt buckles have a retaining member guided in longitudinal slots, wherein the retaining member is displaceable into a retaining position for securing the locking member in the locked state and into a releasing position to release the locking member. A pretensioning spring engages the retaining member and a rod-shaped ...
