Key and motor vehicle equipped therewith

Abstract

In a key, in particular a motor vehicle key, having a key head manufactured from plastic and a bit, which is anchored on the key head and is movable between an idle position and a usage position protruding from the key head, a first part of the key head, on which the bit engages, is manufactured from a fiber-reinforced plastic and a second part, which forms an outer envelope of the key head, is manufactured from a fiber-free plastic.

Description

technical field [0001] The invention relates to a key, especially a car key, and a car equipped with such a key. Background technique [0002] In modern automobiles, a transponder circuit is usually provided on the head of the key, and the transponder circuit can realize remote manipulation of the central control interlock of the car without inserting the key bit into the keyhole. The space required for the circuitry and the buttons required to operate it renders such a key head larger than conventional key heads which serve only as handles for the key teeth of the rotating key. In order to keep the key compact despite this, the key teeth of such keys are usually movable between a use position protruding from the key head and a rest position resting against the key head or even sinking into the key head. . [0003] The mobility of the key bit and the need to be able to transmit torque between the key head and the key bit in the use position place high demands on the load-b...

AI Technical Summary

Problems solved by technology

[0005] The need to use fibre-reinforced plastics significantly limits the possibilities of the external construction of the key

Inhomogeneous material allows essentially only matte key head surfaces to be achieved

The carbon fibers used determine the color of the key head as suggested in said document, so essentially only black or dark surfaces can be achieved
