Abstract
The invention relates to an outer bearing for a backrest, especially of a vehicle seat, comprising a bearing arm (1) for the backrest to which a supporting part (2) is assigned. According to the invention, the bearing arm (1) and the supporting part (2) should enter into a locking connection.
Description
- The invention relates to an external bearing for a backrest, in particular of a vehicle, having a bearing arm for the backrest, which bearing arm is assigned a supporting part, the bearing arm and the supporting part entering into a latching connection and the supporting part having a receiving means for a bolt on the bearing arm.
- Known backrests in vehicles are, if possible, to be able to be folded over, this generally taking place via a rotating joint, in which case corresponding rotating bolts rotate in holes. This requires a considerable effort both for the assembly and for the disassembly.
- DE 296 12 248 U1 and U.S. Pat. No. 5,685,612 each disclose a bearing means for a backrest, in which a bearing pin sits in a guide slot of a supporting part. This guide slot is furthermore assigned a locking lever which is retained in a securing position by a spring.
- The present invention is based on the object of developing an external bearing of the above-mentioned type, in which the assembly operations are considerably simplified, but the backrest can readily be folded over and the bearing means is improved.
- This object is achieved by the bolt being retained by a bearing fork on the bearing arm and the receiving means having two spaced-apart receiving slots which are connected to form a receiving fork, in which case the bearing fork having the bolt can be guided over the receiving fork, so that the bolt slides into the receiving slots.
- The bolt is orientated horizontally in relation to the supporting part and is inserted into the receiving means arranged on the supporting part. For this purpose, this receiving means has the two spaced-apart receiving slots which are formed into side members of a receiving fork. This receiving fork can be bent off from the supporting part, which simplifies the production of the supporting part.
- The bearing fork having the bolt can be guided over the receiving fork in such a manner that the bolt slides into the receiving slots. This means that the respective fork links can be guided in one another.
- The above-mentioned detent pawl which is to be arranged pivotably on the supporting part is provided for securing the latching connection. This detent pawl has a locking slot which in turn has a self-locking locking contour in the region of the receiving slots. The detent pawl preferably sits between the two receiving slots, but it is also conceivable to arrange it outside them, although the bolt then also has to reach above the receiving slots so that a hook of the detent pawl can fit over it.
- In order for the detent pawl to be held in an end position in which it strikes, for example, against a rear wall of the receiving fork, a spring is provided. The spring force and the configuration of the locking contour ensure a play-free operation and an automatic opening of the detent pawl is prevented. The detent pawl opens only under the pressure of the bolt when the bearing arm is to be connected to the supporting part.
- The arrangement the other way around is also to lie within the scope of the invention, that is to say, the receiving fork together with the detent pawl is provided on the bearing arm and the bolt together with the bearing fork is provided on the supporting part.
- Further advantages, features and details of the invention emerge from the following description of preferred exemplary embodiments and with reference to the drawing, in which
- FIG. 1 shows a front view of an external bearing according to the invention for a backrest;
- FIG. 2 shows a side view of the external bearing according to FIG. 1;
- FIGS. 3a) to 3 d) show a perspective view of various working steps in the assembly of the external bearing.
- An external bearing according to the invention has, according to FIGS. 1 and 2, a
bearing arm 1 and a supportingpart 2. Thebearing arm 1 is preferably secured to a backrest of, for example, a rear bench of a vehicle, while the supportingpart 2 is placed onto a chassis. The supportingpart 2 is of angular design and has a set-down plate 3 havingcorresponding holes 4 to place a chassis on or to place onto a chassis. - Protruding from the set-
down plate 3 is aretaining plate 5 from which a receivingfork 6, which can be seen better in FIG. 3a), is angled. This receivingfork 6 has two spaced-apart receivingslots 7, it only being possible to see one slot in the exemplary embodiment shown. The other slot is situated behind adetent pawl 8 which is connected to theretaining plate 5 via a rotating joint 9. - The
detent pawl 8 is of tongue-like design and strikes against arear wall 10 of the receivingfork 6 in an end position. Thedetent pawl 8 is retained in this position by aspring 11. Thespring 11 is connected at one end to thedetent pawl 8 and at the other end to theretaining plate 5 in a positionally fixed manner. In this case, it may be fitted, for example, into aretaining tab 12. - A locking contour13 is formed by a
receiving slot 14. In this case, the locking contour 13 or thelocking slot 14 is designed in such a manner that in its end position, when it strikes against therear wall 10, it is self-locking for abolt 15. In this end position, thedetent pawl 8 fits with ahook 16 over the bolt in such a manner that said bolt cannot slide out of thelocking slot 14. This means that thehook 16 has to fit at least over an upper apex of the casing of thebolt 15. - The
bolt 15 is received in abearing fork 17 which is connected in turn via a connectingplate 18 to thebearing arm 1. - The assembly of the external bearing will be described with reference to FIGS. 3a) to 3 b) . In FIG. 3a), the bearing arm and supporting part are still separate. According to FIG. 3b), the
bearing arm 1 is moved closer to the supportingpart 2, in which case thebolt 15 enters into thereceiving slots 17. In the process, it pushes thedetent pawl 8 out of its end position, as shown in FIG. 3c), with the result that thedetent pawl 8 springs open. This takes place by thebolt 15 rolling along a rounded head of thehook 16. - Finally, the
bolt 15 traverses a hook tip, with the result that thedetent pawl 8 can snap back into its end position which is shown in FIG. 3d). In this end position, thedetent pawl 8 fits with thehook 16 over thebolt 15 and retains the latter securely in this position of use. Thebolt 15 is now used as a rotating bearing for the backrest, with the result that the backrest can be folded over at any time.List of reference numbers 1 Bearing arm 2 Supporting part 3 Set-down plate 4 Hole 5 Retaining plate 6 Receiving fork 7 Receiving slot 8 Detent pawl 9 Rotating joint 10 Rear wall 11 Spring 12 Retaining tab 13 Locking contour 14 Locking slot 15 Bolt 16 Hook 17 Bearing fork 18 Connecting plate
