Definitions

  • the invention relates to a device for producing a electrical contact, in particular for the arrangement in motor vehicle steering wheels, with a first, essentially fixed Contact element, a second, movable against a restoring force Contact element and with an actuator.
  • the contact device sought must be as possible be easy and inexpensive to manufacture and easy on different, often very limited installation conditions have it adjusted.
  • a device of the type mentioned which is characterized according to the invention in that the contact elements from elongated wire or ribbon-shaped sections of material exist, which are defined in a cage parallel to each other are held, alternating areas seen in the longitudinal direction rigid spacer and areas are provided in which the second contact element by means of an actuator elastic deformation of the material section against the first contact element is pressable.
  • the invention assumes that electrically conductive Materials, especially metals, are sufficiently elastic if they exist as wire or ribbon-shaped starting material to cross to be able to be deformed to the extent that the prescribed contact distances can be overcome. Become such material sections parallel to each other in a cage held at a defined distance from each other, you get one Contact device regarding actuation force, restoring force and contact spacing can be freely designed within wide limits because not only the areas provided according to the invention more rigid Spacing and the areas of possible elastic deformation in their longitudinal extent can be varied, but also the Cross section of the material sections, their material and their Elastic properties.
  • the elastic restoring force of such Material sections remains above the usual for motor vehicles Operating times practically unchanged, so that with the once chosen constructive sizes for the cage and the material sections one electrical contact device can be created, the Function parameters do not change.
  • the construction of the contact device according to the invention is very simple. You only have two sections of material in a cage Arrange so that at least one of the material sections is transverse to it Longitude is elastically deformable to the extent that it is suitable Pressed actuation on the other material section can be. The material sections do not have to be further processed are and only require a connection to the electrical Supply system of the motor vehicle.
  • the contact device according to the invention can be executed for any length and therefore also with such actuators can be combined, the several punctiform or a larger area of actuation include.
  • the two material sections do not have to be straight can be arranged, they can be bent in any direction be arranged if they are spaced parallel to each other be held and transverse to their longitudinal extension through the Actuator deformed elastically by the required amount can be.
  • the two material sections do not have to have the same cross-section or made of the same materials consist. The only decisive factor is that one of the two material sections sufficiently elastic and against the other, possibly rigid section of material is pressable.
  • first contact element 1 there is a first contact element 1 arranged parallel to a second contact element 2, wherein also a cage 3 is provided which holds the two contact elements 1, 2 alternately keep a distance, area 4, and in between one Approach of the contact element 2 to the contact element 1 allows Area 5 when the elastically deformable contact element 2 is transverse its longitudinal extent by an actuator 6 elastic is deformed.
  • the contact elements 1, 2 are via connections 1 ', 2' connected to the two poles of an electrical circuit. At The circuit is closed by touching the contact elements and the connected consumer is switched on. Will that over the Actuator initiated force canceled, it turns out Contact element 2 automatically returns to the position shown.
  • With 10 is a supporting component on which the cage 3 rests, or with which the cage 3 is connected.
  • Fig. 2a and 2c can be seen how the Cage 3 can be constructed. It is essentially H-shaped Cross-section (Fig. 2c), alternating in the longitudinal direction the areas 4 that the spacer of the two contact elements 1, 2 guarantee, are present or missing. Between these Areas 4 are areas 5 (Fig. 2b) in which a Approach of the contact element 2 to the contact element 1 nothing in the Way stands.
  • the support member 10 has an upper edge 9 on which the Cage 3 rests. Otherwise, the support element 10 in Areas seen in the longitudinal direction in which the cage 3 rests with alternate areas where below the cage There is free space (see FIG. 2a with 3a).
  • the carrying device (10) can be an airbag housing, for example be, on the upper edge 9 of the cage 3 is arranged.
  • FIG. 3 is a short longitudinal section, as shown in Fig. 2 and a cross section. In this case it is Representation supplemented by the actuator 6, which Cover cap 7 for an airbag module housed in the steering wheel can.
  • Fig. 3 is a support member 10 with a continuous support for the cage 3 shown.
  • Such an embodiment is chosen if the contact element 1 is not subjected to any elastic deformation should be and therefore a continuous abutment in the longitudinal direction required.
  • the actuating force is via the actuating device 6, which has a cover cap 7 projecting in the actuating direction Web 8 can be applied to the contact element 2, the between two areas 4 with rigid spacers, such as shown, can be elastically deformed transversely to its longitudinal extent.
  • the areas 5 in which such an elastic deformation of the Material section is possible, are in their longitudinal extent on the Cross section and the elastic properties of the second contact element 2 matched.
  • the carrying device 10 is not considered to be continuous rigid abutment trained. It has one or more recesses 11 on the elastic dodge of the first contact element Allow 1. In this way, the elastic deformation of the Contact element 1 for resetting the contact element 2 and Actuator 6 can be used. It can also on this way the comfort of the actuator can be improved, by making contact not against a rigid abutment, but against a more or less flexible resistance.
  • a Such embodiment of the support device can also be chosen be when the contact element 1 for setting the desired Contact distance when the actuator is depressed for the first time in the cage 3 irreversible in the direction of actuation by a predetermined amount is slidably arranged. The contact element will taken along in the direction of actuation as far as it is otherwise allows limited actuation of the actuator. The Contact element 1 is then held in this position in the cage 3, whereby the desired contact distance is set at the same time becomes.
