Abstract
Abstract On the edge of the glass receiving frame of the car there is provided a hollow (at 3) weather strip (1) within which two parallel conductors (5) extend spaced apart and are connected to an electric or electronic control unit (7) which is connected to the motor (9) of the power windows and to an outer control switch (11). In case of abnormal working conditions, a squashing of the cavity or channel (3) of the weather strip (1) causes a contact of the conductors (5) closing the circuit connected to a switch reversing the motion of the motor (9) in the control unit (7). A temporary storage causes the window to continue the movement downwardly in spite of other commands sent to the device control unit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
83 words
A safety device for car power windows characterized in that it substantially comprises a hollow (at 3) rubber weather strip (1) extending along the contour of the car glass receiving frame, within which cavity or channel (3) two electric conductors (5) extend parallel to each other and spaced apart when the channel is not squashed, and are connected to an electric or electronic unit (7) reversing the motor rotation, connected with both the windows electric motor (9) and the outer control switch (11).
Claim 2
Dependent Claim
83 words
A safety device for car power windows characterized in that it substantially comprises a hollow (at 3) rubber weather strip (1) extending along the contour of the car glass receiving frame, within which cavity or channel (3) two electric conductors (5) extend parallel to each other and spaced apart when the channel is not squashed, and are connected to an electric or electronic unit (7) reversing the motor rotation, connected with both the windows electric motor (9) and the outer control switch (11).
Claim 3
Dependent Claim
76 words
A safety device for car power windows as claimed in claim 1, characterized in that it substantially comprises a threadlike member (17) or tension wire extending within (3) the hollow weather strip (1) of the glass receiving frame, properly tensioned so that in case of strip compression or squashing, said wire (17) is transversely moved, which causes the closure of a contact (21) and therefore the actuation of the control unit reversing the windows motor (9).
Claim 4
Dependent Claim
81 words
A safety device for car power windows as claimed in claim 1 or 2, characterized in that the hollow (at 3) weather strip (1) of the glass receiving frame is filled with a fluid, such as air, in contact with a sensor (25) connected in turn to the reversing control unit(7), the squashing of the strip (3) causing a displacement of the sensor (25) and therefore actuating the reversing switch of the control unit (7) acting on the windows motor (9).
Claim 5
Dependent Claim
118 words
A safety device for car power windows according to the preceding claims characterized in that the control unit supervising the working of the device, substantially comprises: - a sensor assembly (31) adapted to detect an even slight obstacle interposed between the glass edge and the edge of the interior compartment; - an adapter circuit (33) to convert and adapt a pulse received from the above mentioned sensor (31); - a temporary storage (35) allowing for the device motor (M) to continue driving the window downward until the end of the travel in spite of other commands received by said motor (M); - a circuit (37) controlling the rotation reversal of the motor (M) of the power windows device.
Claim 6
Dependent Claim
75 words
A safety device for car power windows according to the preceding claims, characterized in that the electric control unit proposed as an alternative to the electronic control unit for the device substantially comprises: - a normally open sensor (41), adapted to detect an even slight obstacle interposed between the glass edge and the edge of the interior compartment; and - a reversal arrangement (43) connected through relays with the sensor (41) and the motor (M).
