Abstract
Abstract A locking arrangement for the automotive vehicle doors in which a manipulating means is connected with a locking means in a disengageable connection normally engaged for moving said locking means from the locked position to the unlocked position, or vice versa, as required. The locking means moves together with the manipulating means until the locking or unlocking is completed. After the locking or unlocking is accomplished, the manipulating means can continue further movement for the sake of operating a switching means to connect an energy source with an automatic locking means, leaving the locking means in the locked or unlocked position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
192 words
Door-locking arrangement for automotive vehicles comprising a plurality of mechanical latch means on each door, a plurality of motor means for operating said corresponding latch means, each latch means having a locking member movable between the locked and unlocked positions and a cooperating plate resiliently coupled therewith, each motor means operatively connected to its associated locking member, manipulating means on the door including a movable member inside the vehicle and a key member outside the vehicle, said plate being movable together with said locking member, and further movable by said manipulating means beyond the movable range of said locking member, a common energy source, a control valve for selective supply and interruption of supply of the energy from said energy source to said mOtor means, an electrical switching means for actuating said control valve, said plate being operatively connected both to said switching means and to said manipulating means, said switching means being actuated by said plate when any one of said manipulating means is operated to move said plate beyond the movable range of said locking member whereby said control valve is operated to act on each of said motor means.
