Embodiment Construction

[0017] exist Figures 1 to 3 A key shaft 1 according to the invention for a motor vehicle key 2 made of a copper-nickel-zinc alloy is clearly shown in FIG. The motor vehicle key 2 has a key head 3 with an in particular two-part housing 4 having a first housing section 5 and a second housing section 6 , the key head and the key shaft 1 fixed connection. In the present case, the key shaft 1 is arranged in the housing 4 of the motor vehicle key 2 , wherein the key shaft 1 is injected into the housing 4 of the key head 3 . However, it is also conceivable to pin the key shaft 1 to the housing and / or insert the key shaft 1 into the housing 4 in a non-positive and / or form-fitting manner. A structural space is provided within the housing 4 for receiving the key fob 1 and the electronics unit (not shown in detail). Furthermore, at least two pushbuttons 7 , 8 are arranged within the housing 4 , wherein the first pushbutton 7 is used to open the motor vehicle and the second pushbutton...

Abstract

A key stem (1) for a motor vehicle key (2) is disclosed, wherein the key stem (1) has at least two side surfaces (9, 10, 11, 12), in particular two broad side surfaces (9, 10) opposite each other andseparated by at least one narrow side surface (11, 12), a first broad side surface (9) being provided with at least two different coding strips (13, 14), and a second broad side surface (10) having aflat and non-coded surface (15).

Description

technical field [0001] The invention relates to a key shaft for a motor vehicle key, wherein the key shaft has at least two sides, in particular two broad sides, which are arranged opposite one another and are spaced apart from one another by at least one narrow side. Background technique [0002] A key shaft for a motor vehicle key is known from the prior art, which has two oppositely arranged broad sides and three narrow sides. On both the first wide side and on the second wide side there are respectively arranged coding tracks which are designed identically to one another, so that the motor vehicle key can be used as a so-called steering key. In order to mill the coding track into the key shaft, the key shaft requires a sufficiently large width of at least 3 mm on the narrow side. This results in a larger installation space for the housing of the motor vehicle key into which the key shaft is inserted or connected. As a result, this would result in a larger vehicle key, ...
