DESCRIPTION:
BRIEF SUMMARY
The invention relates to a lock for safety belts having at least two hip strap parts and at least one further strap part.
When safety belts of this kind are used as safety belts for children, the safety belt includes in addition to said two hip strap parts which are attached one at each side of the seat, also two shoulder strap parts which are attached behind the seat, and possibly also a crotch strap part which is attached below in front of the seat and is extended upwards between the legs of the safety belt user. The invention relates particularly to vehicle safety belts of this type with or without the crotch strap part.
A safety belt having five strap parts is disclosed and described in the French patent specification No. 2,116,541. All strap parts in that case are provided with lock tongues which can be inserted into a lock housing including a lock mechanism for co-operation with the lock tongues. On the outside of the lock housing there is a release member which can be actuated manually by several steps for disengagement of the lock tongues of the shoulder straps and for disengagement of the lock tongue of one hip strap part and the lock tongue of the crotch strap part extended upwards between the legs.
It has been noted that one lock tongue or the other of such a lock can be inserted in the lock housing without lockingly engaging the lock mechanism. If this is the case, the safety belt does not, of course, provide the intended protection for the user and in fact the risk of serious injuries to the user may exist should an accident occur, when not all lock tongues are lockingly engaged. In order to eliminate this risk the authorities concerned in some countries have prescribed that there should be obtained an indication of all lock tongues being engaged with the lock mechanism when the safety belt is put into use.
The German utility model registration G No. 8230071.2 discloses and describes a belt lock which satisfies this requirement. The lock is constructed in such a way that the lock housing is attached to one hip strap part and that a lock tongue for co-operation with the lock housing is attached to the other hip strap part. Then, the two shoulder strap parts are provided with fittings which are passed onto projections on the lock housing and/or the lock tongue and are retained on these projections by the lock housing and the lock tongue being lockingly engaged with each other. Thus, it is possible to see directly from the outside if the two shoulder strap parts are attached when the lock tongue and the lock housing are engaged with each other. However, this prior art lock provides the disadvantage that it may be rather difficult to lock the shoulder strap parts, because they must be passed manually onto the projection or projections and must be retained while the lock housing and the lock tongue are being lockingly engaged with each other.
The lock of the invention comprises in a known manner a lock housing to be attached to one hip strap part and enclosing a lock mechanism having a release member to be actuated manually, a lock tongue to be attached to the other hip strap part, which can be inserted into an insert opening in the lock housing for co-operation with the lock mechanism, and a fitting for the further strap part to be connected with the lock housing and the lock tongue by these elements being lockingly engaged with each other.
The purpose of the invention is to provide a lock of a very simple and reliable construction which satisfies the safety requirements now in force and at the same time can be easily handled in use.
The purpose of the invention is achieved by the lock having obtained the characteristics appearing from claim 1, and in order to explain the invention in more detail an embodiment of this lock will be described below with reference to the accompanying drawings in which
FIG. 1 is a plan view of a bottom portion forming part of the lock housing with details mounted thereon and of the lock tongue arranged for co-operation with the lock housing,
