Description

(1) The following are shown:

(2) FIG. 1 a possible embodiment of a transmission means according to the invention with dismantled sealing element,

(3) FIG. 2 the transmission means according to FIG. 1 with a mounted sealing element and

(4) FIG. 3 a possible embodiment of a motor vehicle latch according to the invention.

(5) FIG. 1 depicts a possible embodiment of a transmission means 10 according to the invention. The transmission means 10 hereby has a stop bushing 20, a sealing element 30 and a tensile element 40. The stop bushing 20 for example connects the transmission means 10 to a motor vehicle latch or a handle of a motor vehicle. Fixing elements 26 are arranged on the stop bushing 20. The purpose of the fixing elements 26 is that the stop bushing 20 can be fixed and thus attached to a motor vehicle latch or a handle. The fixing elements 26 can be formed as ratchet or clip connections. FIG. 1 involves two fixing elements 26 which are formed in an elastic/flexible manner and can ratchet into a mounting on the motor vehicle latch or a handle.

(6) Furthermore, the stop bushing 20 has a sealing mounting 21. In FIG. 1 the sealing mounting 21 is formed as a cylindrical mounting, so that a circular sealing element 30 can be arranged therein. The sealing element 30 is preferably arranged flush-mounted to the internal surface 25 of the sealing mounting 21, as shown in FIG. 2. The sealing mounting 21 has four fixing elements 24 in FIG. 1 which are formed as a hole in the sealing mounting 21 or the stop bushing 20. Furthermore, a recess 22 is formed in the sealing mounting 21, through which the tensile element 40, a preferably flexible tensile element 40 is conducted. The collar element 23 forms one end of the stop bushing 20. It is formed as an edge extending from the sealing mounting 21 and encompasses or surrounds the sealing element 30 in the mounted state at least on the cylindrical shell surfaces of the sealing element 30.

(7) The sealing element 30 has a ring-shaped section with the external surface 33 and a conical section 32. Furthermore, the sealing element 30 has a recess 31 for the tensile element 40. The preferably flexible tensile element can be conducted through this recess 31 formed as a hole, whereby in particular a contact between the sealing element 30 and the tensile element 40 can be present, so that no dirt or water can penetrate. The sealing element 30 has fixing elements 34 on one side of the sealing element 30 on which the conical section is not arranged. The pin-shaped fixing elements 34 are shaped in such a way that these can be interlocked with the fixing elements 24 of the sealing mounting 21.

(8) In FIG. 2, the embodiment of the transmission means 10 is shown from FIG. 1, whereby the sealing element 30 is mounted in the sealing mounting 21 of the stop bushing 20. It is apparent that the collar element 23 encompasses/surrounds the sealing element 30 at least in part, whereby the sealing element 30 is protected from external mechanical force impacts and can simultaneously maintain the sealing effect. A housing-type sealing mounting 21, in which the sealing element 30 is fixed thus results.

(9) Furthermore, the handle sections 27 of the stop bushing 20 are apparent from FIG. 2. The handle section 27 has a toothlike structure and increases grip for mounting or dismantling, for example. The handle sections 28 consist of troughs 28 and bridges 28, whereby the ease of handling is also increased. A shell 50 is subsequently arranged on the handle section 28. The shell 50 is preferably flexible. The tensile element 40 is conducted and protected in the shell 50. The shell 50 hereby acts as a mechanical guide for the flexible tensile element 40 and as a counterbearing for the transmitted tensile forces, so that the flexible tensile element 40 can also transmit forces along bends.

(10) FIG. 3 shows a possible embodiment of a motor vehicle latch 100 according to the invention. The motor vehicle latch 100 has at least a latch housing 110 and a latch plate 120. A mounting 121 for the stop bushing 20 of the transmission means 10 is formed on the latch plate 120. The fixing can be performed for example via the fixing elements 26 on the latch plate 120 or the mounting 121. The sealing mounting 21 is arranged within the motor vehicle latch 100 or the latch plate/latch case 120.

(11) According to the invention, the sealing mounting 21 now prevents the sealing element arranged in the sealing mounting 21 from being damaged in the mounting of the transmission means 10 on the motor vehicle latch 100 as shown in FIG. 3.

(12) The tensile element 40 is conducted through the shell 50 and the stop bushing 20 into the motor vehicle latch 100 and is fixed there to an operating lever 130. The shell 50 and the stop bushing 20 can be formed or interlocked as a single component, in particular in a materially uniform manner.
