Definitions

• the invention relates to a key vehicle starting means with a protection of said key, a protective cover for a starting key to secure the key, as well as a vehicle equipped with such a starting means .
• the key starting device is in the form of a lock which comprises a stator in which a barrel pivots. Turning the barrel using a key allows the vehicle to be powered up in one position, possibly with the release of the steering column, and in another position the vehicle being powered down, possibly with the locking the steering column.
• This setting in rotation of the barrel is carried out by the mechanical key inserted in the barrel.
• the mechanical key comprises a gripping part, intended to be taken in the hand by a user, and a rod intended to be inserted into the barrel.
• the shank of the key has a shape specific to the barrel, such as for example a succession of teeth, which allows said barrel to rotate. The rotation of the key inserted in the barrel is obtained by acting on the gripping part which remains outside the barrel.
• the barrel has several angular positions.
• a first position corresponds to a so-called “stop” position in which the vehicle is switched off, generating a locking of the steering column, with the electrical and electronic equipment that cannot be activated.
• a second so-called “contact” position allows the energizing certain electrical and / or electronic vehicle equipment, as well as unlocking the steering column.
• this second position can also allow the activation of the driving controls and of the electric motor in order to move the vehicle forward.
• the barrel has a third so-called "starting" position allowing the activation of a starter launching the thermal engine.
• one of the aims of the invention is to provide a starting means with a key starting device making it possible to secure the key in said starting device while allowing the actuation of the starting device by the key.
• a starting means comprising a key starting device comprising a stator in which a barrel pivots between a first position and a second position along an axis of rotation, the barrel opening on a front face of the stator, a mechanical key comprising a rod inserted into the barrel on the side of the front face of the stator, and a gripping part at one end of the rod and located outside the barrel, so that a rotation of the key along the axis of rotation between a first position and a second position rotates said barrel.
• Said starting means comprises on the one hand a cover comprising an interior space opening onto an insertion face of said cover and receiving the gripping part of the key, means for driving in rotation the gripping part of the key of so that a rotation of the cover along the axis of rotation drives the key in rotation along the same axis of rotation, and a holding interface, and on the other hand a means of holding the cover connected to the stator and cooperating with the holding interface, arranged so as to block the cover in translation parallel to the axis of rotation preventing it from moving away from the stator and to leave said cover free to rotate relative to the stator and to the barrel along the axis of rotation between the first position and the second key position.
• the cover secures the key because said key cannot be removed from the barrel, blocked by the cover retained by the holding means, while having the possibility of turning the key to actuate the starting device.
• Another advantage is the simplicity of production because it can have only two parts.
• Another advantage is that this means makes it possible to keep a standard starting device consisting of a stator and a barrel in which the key is inserted because the cover is not attached to the barrel. In the event that a conventional starting system in which the key can be removed is to be installed, the cover is not installed. Conversely, in the case where it is desired to activate the starting device by turning the key without the user being able to remove the key, for example in the case of vehicle sharing, it suffices to '' install the starting device with the cover.
• the system is particularly suitable for versions of vehicles intended to be shared, by installing in addition a start authorization system by digital key recognition, such as using a smartphone or a wireless connection system: the digital key authorizes the activation of the vehicle following the actuation of the hood which rotates the key between a stop position and a start position.

• the cover is blocked in translation by the blocking wall and cannot be removed by pulling on it to move it away from the stator, in a simple manner, by abutting the shoulder against the wall of locking, while allowing rotation of the cover around the axis of rotation so as to rotate the key inserted in the cylinder.
• the key is not accessible, and therefore secure, at our lowest cost.
• the cover comprises a body extending longitudinally parallel to the axis of rotation from the shoulder, and whose section over its entire length is of smaller dimension than the section of the opening .
