DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a buckle for a safety belt for vehicles, which comprises a tongue-shaped insertion part and a sleeve-shaped receiving part exhibiting a locking means, hereinafter called "the primary lock", which is provided for locking the insertion part, when it is in an inserted position in the receiving part, and for permitting its release from such a locked condition, the primary lock being designed as an arm, which is pivotable round a shaft, which is parallel to the plane of the insertion part and perpendicularly arranged relative to the direction of movement of the insertion part in the receiving housing, which primary lock is provided with one or several engaging pins serving the purpose in a first pivoting position (locking position) to cooperate with a counter pin on the insertion part and lock the same to the receiving part, and in a second pivoting position to release the insertion part, the primary lock being spring loaded in the releasing direction and provided with a stop dog, which is in cooperation with a locking means displaceable along the stop dog, hereinafter called "the secondary lock", arranged to impede the primary lock from pivoting in the releasing direction into a displacing position (locking position) of the secondary lock, whereas the secondary lock permits pivoting of the primary lock into a second position of displacement (release position) of the secondary lock, said primary and secondary locks for the purpose of releasing the locking mechanism being actuated by a manually operated device, which can be displaced in the direction of insertion of the inserting part.
It is a principal object of the invention to provide a reliably functioning means of the kind mentioned, which is of as simple design as possible.
Said purpose is reached by the invention, which substantially is characterized by the primary lock comprising a double armed lever, i.e. a lever extending on both sides of said pivoting shaft, the one arm of said lever, which is pointing in outwards direction, i.e. in direction towards the opening of insertion, supporting said stop dog, which cooperates with the insertion part, and the inwards pointing arm of said lever supporting said stop dog cooperating with the secondary lock, which last mentioned stop dog is formed by a surface, which is facing in the same direction as the direction, in which the projection supporting the stop dog cooperating with the insertion part is projecting.
The invention is described in the following, reference being made to the accompanying drawings, in which
FIG. 1 is a view of a longitudinal cross section through a buckle designed according to the invention,
FIG. 2 is a partly sectional view of the same buckle as seen from above in FIG. 1,
FIG. 3 is a view substantially corresponding to the one in FIG. 1 and schematically showing a longitudinal cross section through a variant of a buckle designed according to the invention,
FIG. 4 is a view substantially corresponding to the one of FIG. 2 and schematically showing a top view of the buckle illustrated in FIG. 3,
FIG. 5 is a view corresponding to the one in FIG. 3 and showing a longitudinal cross section through a buckle according to another variant of embodiment,
FIG. 6 is a view corresponding to the one of FIG. 4 and showing the buckle illustrated in FIG. 5,
FIG. 7 is a view corresponding to the one of FIG. 3 and showing a longitudinal cross section through a buckle of still another variant of embodiment according to the invention,
FIG. 8 is a view corresponding to the one of FIG. 4 and showing the buckle illustrated in FIG. 7,
FIG. 9 is a view corresponding to the one of FIG. 7 and showing a longitudinal cross section through a buckle designed according to still another variant of embodiment of the invention, and
FIG. 10 finally being a view corresponding to the one of FIG. 8 and showing the buckle illustrated in FIG. 9.
The buckle, which is illustrated in FIGS. 1 and 2, comprises a tongue-shaped insertion part, in its entirety indicated with 1, and a sleeve-shaped receiv
