Device for automatically closing a power roof of a vehicle
First Claim
1. A vehicle, comprising a power roof having a closed position, a first open position in which said roof is translated from said closed position and a second open position in which said roof is rotated from said closed position;
- an electric motor for moving said roof between said positions;
a source of electricity for said motor;
means for securing said vehicle against theft, said securing means having an operative condition and an inoperative condition; and
means for connecting said motor to said source, said connecting means including circuit means coupled to said motor and said source, first switch means for closing said circuit means and second switch means for closing said circuit means, said motor being designed to translate said roof towards said first open position when said first switch means is closed while said roof is in said closed position, and said motor further being designed to rotate said roof towards said closed position when said first switch means is closed while said roof is in said second open position, said motor also being designed to rotate said roof towards said second open position when said second switch means is closed while said roof is in said closed position, and said motor additionally being designed to translate said roof towards said closed position when said second switch means is closed while said roof is in said first open position, said circuit means being operable to actuate said switch means in response to a change from the inoperative to the operative condition of said securing means such that said motor locks said roof in said closed position.

Abstract
A motor vehicle has a power roof which can either rotate between a first open position and a closed position or translate between a second open position and the closed position. An electric motor for opening and closing the roof operates from a battery of the vehicle and is connected to the battery by a circuit which can be closed by either of two switches. When the roof is closed, activation of one switch causes the roof to open by rotation while activation of the other switch causes the the roof to open by translation. When the the roof is in an open position, activation of the switch other than that which caused the roof to assume such position effects closing of the roof. The vehicle is equipped with a security system which also operates from the battery and, upon activation, sends a signal to the circuit connecting the motor to the battery. In response to this signal, the circuit issues a short first pulse, a second pulse which is at least as long as the first pulse, a short third pulse, and a fourth and final pulse which is at least as long as the third pulse. The first and fourth pulses activate one of the switches while the second and third pulses activate the other switch. This causes the roof to close completely regardless of the position of the roof at the time the security system is activated.
