Abstract

An automotive door lock arrangement comprising a door lock of latch type provided for each of all doors of an automotive vehicle, said arrangement being characterized by the provision of: a solenoid coil assembly comprising a locking coil means and an unlocking coil means provided for each of said doors, an automatic switch means connected with the driver'"'"''"'"'s solenoid assembly for sensing starting of said vehicle, electric wiring means connecting all of said solenoid assemblies with each other, said door locks being actuated thereby into their locking position when the driver'"'"''"'"'s locking coil means is energized for locking by receiving an electrical signal depending upon said energization.

Claims

1. A door lock arrangement for use on a vehicle having a plurality of doors, each having manual control means for locking and unlocking said doors, comprising a solenoid coil assembly mounted in each door and having a coil locking portion, a coil unlocking portion and a common reciprocal armature means operably connected to said manual control means, electrical circuit means connecting said coil assemblies including power means, first switch means operable upon movement of a selected manual control means to the locking position to complete an energizing circuit to the locking coil portion of each of the coil assemblies associated with the remaining manual control means to shift said remaining manual control means to the locking positions thereof and second switch means operable by the movement of said remaining manual control means to the locking position to open said energizing circuit.

2. A door lock arrangement as set forth in claim 1 further comprising additional circuit means for automatically energizing the locking coil portion of each of said coil assemblies responsive to a vehicle condition including ignition switch means and vehicle condition responsive switch means arranged in series with said power means, said vehicle condition responsive switch means having first contact means arranged to complete a circuit through the coil locking portion of the coil assembly associated with said selected one of said manual control means and second contact means arranged to energize the coil unlocking portion of said coil assembly.

3. A door lock arrangement as set forth in claim 2 wherein said vehicle condition responsive switch means is comprised of drive means adapTed to be rotated upon movement of the vehicle, magnetic means connected to said drive means for rotary movement, and magnetizable means adapted to be moved on rotation of said magnetic means to shift said vehicle condition responsive switch means into engagement with said first contact means and spring means adapted to shift said vehicle condition responsive switch means into contact with said second contact means upon cessation of rotation of said magnetic means.
