Abstract

The instrumentation unit for a car has a profiled console mounted under the steering column with the controls grouped along each side, and with the instruments in compact groupings over the front. Interconnections are made inside the console using printed circuit boards. The layout is simple, with suitable access panels spaced about the console. The controls are arranged so that they are easily and rapidly reached by the driver.

Description

Arrangement for actuation elements and associated

Functional elements The invention relates to an arrangement for in the area of the steering wheel arranged actuating elements and for associated functional elements for operating devices in a motor vehicle.

It is known to use actuating elements according to ergonomic aspects Easily accessible in the area of the steering wheel on the outer surfaces of an instrument panel and steering wheel located housing to be arranged. This arrangement has the disadvantage that by the accumulation of actuators on the housing for mostly electrical Facilities many lines, or a thick cable harness, to those distributed in the vehicle Functional elements must lead. Due to the large number of cables, the electrical links Confusing and therefore not very service-friendly. A pre-assembly and pre-inspection of the actuating devices is only possible to a limited extent.

The object of the present invention is to provide an inexpensive manufacture and mountable, as well as functionally reliable arrangement of actuating elements and associated Functional elements or function transmitters, such as flasher units, relays, electronic circuits, To create fuses, etc., for devices on a motor vehicle.

According to the invention, the object is achieved with the characterizing features of claim 1 solved.

When combining actuating elements according to the invention and functional elements to a structural unit is advantageous that long Cable routes, which are both expensive, as well as through z. B. Interruptions cause Can give disturbances, omitted and thus the arrangement according to the invention inexpensive and is functionally reliable. Another advantage is the possibility of unity to be pre-assembled from actuating elements and functional elements during vehicle production and to be provided on the final assembly line already checked. In the event of malfunctions it can be advantageous can be repaired on a unit and not, as was previously the case, on those distributed in the vehicle Components, with the additional benefit of checking long cable runs between Actuating elements and functional elements are not required.

With an arrangement based on ergonomic criteria The space in the vicinity of the steering wheel is occupied by actuators. In one embodiment according to claim 2, the space between the steering wheel and the instrument panel is advantageously used by the structural unit attached here, the actuating elements on the outside of a housing within easy reach of the steering wheel and the function generator are arranged in housing.

An embodiment according to claim 3, wherein at least some parts the structural unit are designed to be pluggable, is very easy to assemble and service-friendly. The parts can be arranged in a mounting frame, with the housing only serves as a cover, or the housing itself supports plug-in bases and components, flaps or cover plates being advantageously attached to the housing so that parts can be changed easily.

Those required for electrical equipment are advantageous Fuses according to claim 4 also arranged in the structural unit.

In one embodiment according to claim 5, the fuses are through a flap accessible on the structural unit.

The fuses are therefore easy to check and can be checked by the driver of the vehicle comfortably in the interior of the vehicle in the event of an electrical unit failure change.

In the structural unit made up of functional elements and actuating elements the function control lamps are advantageously integrated according to claim 6.

Thanks to the concentrated arrangement of actuating elements and function transmitters In a small space it is possible to use the wiring in the form of prefabricated units, such as printed circuits, film technology, punched tracks, etc. so that they can be manufactured very inexpensively and achieve a high level of functional reliability can.

The instrument cluster or the display unit is advantageous the unit is also connected in a pluggable manner.

The arrangement according to the invention is based on an exemplary embodiment described in more detail below.

Figure 1 shows schematically the arrangement of the structural unit.

Fig. 2 shows a section A-A 'through the structural unit with a possible arrangement of the components.

In FIG. 1 lies between the steering wheel 1 and the instrument panel 2 of a motor vehicle, a housing 3. Actuating elements are located on the outer surfaces of the housing 3 4, function control lamps 7, e.g. check package displays, and a flap 6.

The display unit (8) is connected to the unit in a pluggable manner.

The actuating elements 4 act on functional elements built into the housing 3, such as B. flasher units, relays, switching and control electronics, check package elements. The fuses for the electrical units of the motor vehicle are easy accessible under the flap 6.

In Fig. 2 is the arrangement of the actuating elements 4, the function control lamps 7 and the multiple plug 10 on the outside of the housing 3. the Functional elements 11, or function generators are in jacks 9, which either are arranged on the inside of the housing or on separating bubbles 12, held. Electronics plug-in cards 13 are inserted between metal dividers 12.
