DE2225023C2 - Housing of variable depth, especially for exterior rearview mirrors for motor vehicles - Google Patents

Description

The invention relates to a depth-variable housing door, in particular motor vehicle exterior rear-view mirrors according to patent 1,430,355.

In the case of the outside rearview mirror according to patent ί 43!) 355, the housing consists of a rear one Housing part in which at least one is located against the increasing shock-absorbing resistance Compression spring several front housing parts up to the stop at the opening edge of the rear housing part can be pushed in, the depth of the housing is constantly decreasing and in the end position corresponds approximately to the depth of the inner housing part.

A disadvantage of the subject matter of the main patent is when the outside rearview mirror is attached to the side of the vehicle door instead of further to the front on the fender, that when the outside rearview mirror begins, it is mutually exclusive! ^p Dung around the front housing parts, their opposite to the rear housing part

- certainly given in the georatich position

- Lose leadership and be able to make uncontrolled movements by yourself, in the event of a Impact from a strongly oblique to the housing longitudinal center axis running direction a clean pushing into one another of the individual housing parts- *, hinders and also the front wheels of the telescopic housing parts that point in the direction of travel In places, more can be exposed than in the '' eresse of the more accident-free design desired ^

The invention is based on the object of an in to create a housing that can be varied in depth, especially for exterior rearview mirrors for motor vehicles, that avoids the disadvantages of the subject matter according to the main patent and that is the same Also good for exterior rearview mirrors of the types to be attached to the front doors of a vehicle can be used, which is in accordance with the newer international safety regulations with a Impact from the front, diagonally from the ... His or from Can lay flat against the body or door at the rear.

According to the invention this object is achieved in that at least one front housing part with the himeren h? «·· Rasis housing part, which supports the adjustable mirror glass carrier, through a common Axis is connected in a force-controlled manner, wi / oei the front housing parts in is known to result from at least one the spring supporting the rear housing part are held in their end-of-use position.

Further features characterizing / extending the invention are specified in the subclaims.
