ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a security system for a motor vehicle opening leaf including means for detecting the approach of a user's hand.
The invention relates more particularly to a security system for a motor vehicle opening leaf, of the type in which the system comprises a handle, of which an external lever for grasping is articulated to a handle support arranged on the inside of a bodywork panel, the lever being moved by a user from a position of rest as far as a position of opening so as to operate a lock which keeps the opening leaf in the closed position, of the type in which the security system includes means for remotely detecting, by means of an electromagnetic signal, the presence of a user's hand near the handle, and of the type in which the detection means include a control circuit and at least one sensor capable of emitting or of receiving the electromagnetic signal.
BRIEF SUMMARY OF THE INVENTION
More specifically, the object of the invention is to propose a design of detection means which allow easy integration of the security system into the opening leaf when the vehicle is being constructed.
Specifically, the problem involves being able to mount these detection means easily on the opening leaf while at the same time ensuring the correct relative positioning of the various components of the security system and while at the same time guaranteeing that the detection means which involve sensors and electronic circuits which are somewhat delicate are appropriately protected.
To this end, the invention proposes a security system for a motor vehicle opening leaf, of the type in which the system comprises a handle, of which an external lever for grasping is articulated to a handle support arranged on the inside of a bodywork panel, the lever being moved by a user from a position of rest as far as a position of opening so as to operate a lock which keeps the opening leaf in the closed position, of the type in which the security system includes means for remotely detecting, by means of an electromagnetic signal, the presence of a user's hand near the handle, and of the type in which the detection means include a control circuit and at least one sensor capable of emitting or of receiving the electromagnetic signal, wherein the detection means are arranged in a casing which is fixed by elastic snap-fastening on an external face of the handle support so that a window made in an external face of the casing lies facing a window formed in the bodywork panel.
According to other features of the invention:
the casing includes positioning pegs which extend transversely inward from an internal face of the casing and which are intended to be housed in corresponding orifices formed in the external face of the handle support;
the support includes elastic tabs which extend transversely outward and which collaborate with catching lugs of the casing so as to fasten the casing to the support;
the casing is produced by injection-molding of plastic, and includes a connector body molded integrally so as to allow the control circuit to be connected to an antitheft unit;
the connector body extends vertically as a downward protrusion from a main body of the casing in which the control circuit and the sensor are arranged;
the connector body extends roughly in a plane which is parallel to the plane of the bodywork panel and which is offset transversely outward with respect to a plane in which the main body of the casing extends;
the window in the casing is delimited by a tubular wall which extends transversely outward and on which there is overmolded a seal intended to collaborate with a complementary tubular skirt belonging to a cover which is made of a material that is transparent to the electromagnetic signal and which closes off the window in the bodywork panel;
the detection means include a switch which is intended to be operated by an actuator of the security system, the switch is arranged inside the casing facing an opening which is formed inside the internal face of the casing and which lies facing a corresponding opening formed in the handle support so that the switch can be operated by the actuator through the two corresponding openings; and
the actuating opening formed in the casing is closed in leaktight fashion by a flexible membrane which is deformed by the actuator to operate the switch.
