Partial opening systems for motor vehicle doors

Abstract

The invention relates to a partial opening system (20) for a motor vehicle door leaf (12), comprising: an actuator (22) comprising a fixed frame (24) mounted on the door leaf (12) and retractable An actuating element (26) that moves between a position in which the actuating element (26) allows the door leaf (12) to assume its closed position in a retracted position and a deployed position in which the free end of the actuating element (26) is adapted to be carried on the central pillar (18) for partially opening the door leaf (12); and means for holding the door leaf (12) comprising a Retaining end piece (38) and retaining element (40) adapted to be mounted on the center pillar (18) of the vehicle (10), the retaining device being designed to retain the door leaf (12) in its retracted position and in the user's The door leaf (12) is released in the event of an opening action of the door leaf (12), the holding device being mounted to pivot freely about an axis exactly parallel to the opening axis of the door leaf on the free end of the actuating element of the actuator.

Description

technical field [0001] The invention relates to a system for actuating a motor vehicle door leaf between a closed position and a partially open position. Background technique [0002] Typically, a motor vehicle door leaf has a first front edge adapted to be pivotally mounted on the frame of the motor vehicle about an opening axis; and a second, opposite rear edge designed to extend completely parallel to the central pillar of the motor vehicle . [0003] A motor vehicle door leaf is known which does not have a mechanical door handle, which is replaced by an electric opening device. [0004] The electrical opening means of the door leaf can be controlled via a contactless interface or via a tactile type interface with capacitive or inductive sensors, for example to allow a user to control the opening of the door leaf. [0005] In addition, to overcome the problem of not having a mechanical handle and thus no gripping element allowing the door leaf to be opened, the door lea...

AI Technical Summary

Problems solved by technology

[0014] A disadvantage of the automatic partial opening system described above is that, in the event of a malfunction, the door leaf runs the risk that it can no longer be manually operated by the user, the door leaf runs the risk of remaining blocked in the open or closed position

Furthermore, the partially open position of the prior art is unstable and there is no information as to whether the door has been pulled by the car user
