Abstract:
This electrical switch (1) consists of a flat spring, profiled in order to provide both a contact function and a spring function; the flat spring (1) includes a first leg (2) which can be deformed by bearing on a fixed pivot pin (3) of a support (4), and a second leg (5), which can move at the same time as the first leg deforms and whose end (5a) can assume either of two positions for contacting pins (14,15) of an electrical circuit. The switch according to the invention is less bulky than the usual switches by virtue of its flat shape, less expensive to manufacture, because it only consists of a single component, and easy to install on its support.
Abstract:
An electric motor comprising a rotor and a stator which comprises two magnetic blocks fixed in confronting relation on a frame of iron or magnetic sheet. The blocks are respectively fixed on two support elements which are interconnected by two covers of iron or magnetic sheet attached to the support elements on each side of the magnetic blocks. An end element for supporting the shaft of the rotor is disposed at each end of the frame. The covers are provided at their ends with positioning notches which are cooperative with bosses provided on the end elements.
Abstract:
This motorized reduction gear includes a toothed wheel (1) for driving an output member mounted on its hub (4), and one or more damping springs (6) interposed between the wheel (1) and the output member; the damping spring(s) (6) is(are) flat and metal and formed of two flexible branches (7) which are symmetrical with one another with respect to a median plane; each branch includes a convolution, a first section (8) of which extends around the hub (4), is extended by a fold (11), and a second section (9) terminated by a radial segment (12), a flat (13) for bearing on a rib (17) of the wheel (1), and a claw (14) for holding the spring in the wheel (1), around the hub (4). When the window pane comes to rest in abutment at the end of its path, one of the branches (7) is compressed and moves closer to the other, damping out the halting in the rotation of the toothed wheel (1). This(these) spring(s) has(have) a small overall size and high operational stability.
Abstract:
The window lifter (1) may, for example, be of the twisted cable type (3) driven by a motorized reduction gear (2) wound around return pulleys (4, 5) and sliding in a guide rail (6); a carriage (8) carrying the window pane (9) is fixed to the strand of the cable passing into the rail (6); damping elements (11) such as flat metal springs, for example, are fixed to the ends of the guide rail (6) and to the door panel (7), which makes it possible to damp out a hard impact against an obstacle encountered by the window pane (9).
Abstract:
The actuator comprises the following elements:(a) an electric motor (2) capable of driving in rotation a reversible lead-screw (3) on which is mounted a carriage (4) which is freely slidable and mechanically connected to a lever for locking the latch;(b) a nut (6) mounted on the lead-screw (3) within the carriage, prevented from rotating by a guiding of the nut within the carriage and provided, on one hand, with an elastically yieldable element (7) compressible between the carriage (4) and the screw (3) so as to return the nut (6) when the element (7) is compressed, and, on the other hand, with a stud (8) adapted to cooperate with ramps (9, 10, 11, 12) formed on a cam (13) vertically movable in the case by the movement in translation of the nut (6) and the stud (8) controlling the cam (13);(c) the cam (13) is provided with a shoe (15) capable of bolting the carriage (4) in the electrically locked position when it has been displaced to its uppermost position by the stud (8) sliding on the ramps, whereby any manual unlocking of the latch is prevented.
Abstract:
Actuator for an electrically operated vehicle door lock has an actuator plunger which is shiftable between first and second positions to lock and unlock the related door latch. The actuator plunger carries a resilient electrical contact element which coacts with one or more fixed contacts on a guide to close one or more respective circuits for operating other parts of the related system and/or signalling the condition of the related lock, such as whether it is locked or unlocked. Preferably the contacts slide into and out of engagement to provide silent operation and self-cleaning wiping action.
Abstract:
A two buss system to accomplish; 1) communication from contact pairs located at vehicle access points such as a vehicle door or trunk to a central controller; and 2) transmitting current for energization of actuators to implement respective commands such as normal lock or super lock. The contact pairs function to provide entry ports for commands as well as providing status signals of various points of interest. The contact pairs are connected to individual output ports of a counter. Each contact pair is sequentially pulsed by a single pulse of a pulse train provided by the central controller. If a contact pair is engaged or closed when pulsed, the pulse will cause a coincident buss loading to occur. The central controller monitors buss loading and is appraised of the contact status by the coincidence (or lack thereof) of a pulse and a respectively loaded buss. Upon determination of the contact statuses, the central controller accesses a look-up table and then implements the respective commands by energizing one of several relays that define path for flow of current to respective actuators.
Abstract:
An actuator which is physically secured to the locking mechanism by means of a first electrical connector. The motor of the actuator is provided with power through a second electrical connector which supplies power thereto through the first connector. The second connector also provides connection to a status contactor which provides locked and unlocked status indication. In this manner, the second connector accomplishes a dual function. Consequently, fasteners as required to secure the actuator to the lock mechanism are eliminated. A modular assembly is thus produced in which the interface housing carries a single connector which can be easily connected to the cable harness of the vehicle. Therefore only one electrical connection is required when mounting the lock in the door of the vehicle.
Abstract:
The generator comprises means (2) for adjusting and an associated calculator, the adjusting means (2) comprising an endless rotative knob (4) capable of rotating through a given angle of which the position of the element to be controlled is a direct function, and pulse generating means (15, 17) generating a number of pulses which is proportional to the angle of rotation of the knob (4) and means for counting said number, and a selector of the direction of rotation. The calculator is programmed to determine, from the number of pulses counted, a proportion of the path the movable element must travel through realtive to end-of-travel means. The instruction determined by the calculator is then transmitted to a motor driving the movable element and to a position copying device. The invention permits obtaining a fine continuous, or substantially continuous, adjustment by a simple rotation of the knob. Application in particular to the control of opening elements of automobile vehicles.
Abstract:
Devices for controlling the unlatching and locking of the latch are hydraulic. Connected to a single unit having a plurality of slide valves are an expansion vessel, transmitting pumps controlling the unlatching, a receiving unlatching fluid motor and one or more pumps controlling the locking of the latch. Depending on which slide valves and pumps are employed, it is possible to achieve at will one or more of the various locking functions required in automobile vehicle latches.
