Abstract

Abstract A safety device for a motor-operated window regulator used for raising and lowering the window of a vehicle including an elongated sheath which is elastically deformable located outside the plane of the window for detecting the presence of an obstacle hindering the closure of the window. Electric conductors are positioned within such sheath and such conductors are slightly separated and adapted to contact each other upon a light deformation of the sheath by such obstacle. A device is responsive to the contact of the conductors for reversing the operation of the motor thereby preventing any risk of accidental closure of the window.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 148 words
A safety device for a motor operated window regulator used for raising or lowering the windows of a vehicle comprising: a. a sheath which is elastically deformable located outside the plane of said window for detecting the presence of an obstacle during the closure of said window; b. continuous electric conductors positioned within said sheath and extending the entire length thereof, said electric conductors being slightly separated and adapted to contact each other upon a slight deformation of said sheath by said obstacle; and c. a relay adapted for connection to a power source through said electric conductors when an obstacle is detected during raising of the window, said relay having double-pole contacts located in the energizing circuit of the motor and adapted to reverse the operation of the motor so as to cause lowering of the window and prevent any risk of accidental squeezing of the obstacle.
Claim 2
Dependent Claim 148 words
A safety device for a motor operated window regulator used for raising or lowering the windows of a vehicle comprising: a. a sheath which is elastically deformable located outside the plane of said window for detecting the presence of an obstacle during the closure of said window; b. continuous electric conductors positioned within said sheath and extending the entire length thereof, said electric conductors being slightly separated and adapted to contact each other upon a slight deformation of said sheath by said obstacle; and c. a relay adapted for connection to a power source through said electric conductors when an obstacle is detected during raising of the window, said relay having double-pole contacts located in the energizing circuit of the motor and adapted to reverse the operation of the motor so as to cause lowering of the window and prevent any risk of accidental squeezing of the obstacle.
Claim 3
Dependent Claim 23 words
A safety device as defined in claim 1, further comprising a timing device for maintaining the relay energized for a predetermined time interval.
Claim 4
Dependent Claim 16 words
A safety device as defined in claim 2, wherein said timing device is a pneumatic device.
