Door handle which is intended, in particular, for a motor vehicle comprising an inertial safety system
The invention relates to a door handle which is intended, in particular, for a motor vehicle. The inventive handle comprises a lever ( 105 ) which can rotate around a first axis ( 107 ) in a frame ( 101 ) that is intended to be fixed to the door ( 102 ) and which is mechanically connected to a mobile fitting that can be intercepted by a locking element which is articulated to the frame ( 101 ) or a body which is solidly connected to the frame, such as to pivot around a third axis ( 117 ) from a rest position to an active position. In this way, if pivoted violently, the locking member ( 116 ) strikes the aforementioned mobile fitting and prevents same from moving. According to the invention, the handle also comprises a piece ( 200 ) for blocking the locking element in the active position thereof.
1. A door handle for a motor vehicle, comprising:
a lever configured to rotate about a first axis in a frame intended to be fixed to the door and is connected mechanically to a mobile fitting able to be intercepted by a locking element hinged to the frame or to a body fastened to the frame, wherein the locking element pivots about a third axis from a rest position into an active position, in such a way that, during sudden pivoting of the locking element, the locking element strikes said mobile fitting and prevents its displacement,
wherein said door handle also comprises a part for blocking said locking element in its active position.
2. The door handle as claimed in claim 1 , wherein said mobile fitting is a swivel wheel which can rotate inside said frame about a second axis when the lever is pulled so as to open the door, said swivel wheel having a shoulder able to be intercepted by a stop piece forming part of said locking element comprising a lever of the rocker arm type which is provided with an inertial mass, the stop piece striking the shoulder and preventing rotation of the swivel wheel during sudden pivoting of the rocker arm.
3. The handle as claimed in claim 2 , wherein said rocker arm has a lug on its side opposite to that carrying said stop piece, this lug engaging with said blocking part, in the active position.
4. The handle as claimed in claim 3 , wherein said blocking part consists of a resilient blade fastened to the frame and having an opening for engagement of said lug, in the active position.
5. The handle as claimed in claim 4 , wherein said blocking blade is calibrated to be prestressed so as to press against said lug in the rest position.
