ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a force-responsive longitudinally extending sensor, comprising a flexible longitudinally extending support having a predetermined width, first and second sensing means mounted on the support and spaced apart across the width of the support and extending therealong in substantially parallel configuration so as each to produce a respective signal in response to a respectively applied force.
Such sensors may be used, for example, in motor vehicles for detecting the presence of an obstruction in a window opening closable by a motorised window pane. However, such sensors may be used in many other applications.
DESCRIPTION OF THE PRIOR ART
One form of such a sensor is shown in DE-A-21 57 597. Here, the support comprises a channel-shaped window-glass receiving and sealing channel, the first and second sensing means being respectively positioned on and running along the two distal edges forming the longitudinal mouth of the channel. With such an arrangement, the two sensors must be separately mounted on the channel edges. If this is done after insertion of the channel into its rigid mount, two separate operations are necessary. If the sensors are mounted on the channel before the channel is mounted in its rigid frame, the sensors may be liable to damage during handling.
The invention aims to deal with these problems.
BRIEF SUMMARY OF THE INVENTION
According to the invention, therefore, the sensor as first set forth above is characterised in that the support is a substantially planar base.
