  The invention relates to a sliding type door to a sliding door for a motor vehicle

sliding for vehicle.

  The invention more particularly relates to a sliding door for a motor vehicle, which is provided with at least one unlocking means, it comprises connecting means cooperating with guide means, the connecting means are secured to the opening, the Guiding means integrated into the vehicle structure are guide rails

  arranged longitudinally to the vehicle.

  The design of new city-based vehicles meets the dimentional requirements that combine to reduce the exterior dimensions of the vehicle while increasing the livability of the interior space.

  as well as a large number of features.

  To meet the need for accessibility to the passenger compartment, it is known to use a sliding type opening disposed on at least one side of the vehicle. Indeed, the sliding doors used on motor vehicles are recognized for their practicality of operation, allowing easy access to the passenger compartment. Commonly used on vehicles of large size, unibody type, this type of opening sees its diversified application on city vehicles. In this particular application, at least one side of the vehicle comprises an opening sliding door type, which must then promote access

  in the front and rear seats of the vehicle.

  Sliding door type doors are linked to the structure of the vehicle by means of connection sometimes identifiable to arms. These connecting means cooperate with guiding means arranged longitudinally on the vehicle structure, commonly constituted by guide rails. Different architectures designed to optimize the movement of the opening on the structure of the vehicle are

thus known.

  When the maneuver of the movement of the opening is done manually, it is customary to have at least one inner handle ensuring the gripping function. This inner handle is positioned on a door panel in the middle position. This inner handle has two main functions, namely that of unlocking the door and that of gripping so that at least one occupant of the vehicle can transmit the necessary energy

to the displacement of the opening.

  A first drawback relating to this type of door arrangement on a city car lies in the loss of the grip occurring during the opening / closing maneuvers, mainly due to the passage of the handle in an access zone limited by the presence a seat back. When two rows of seats are juxtaposed, access to the seats is favored by a longitudinal displacement of the sliding door. The gripping means present on the inner door panel crosses the edges of the backrest of the first row of seats, thus making it difficult to maintain the gripping means on the door.

  the entire displacement of the opening.

  A second disadvantage lies in the impossibility of integrating a holding handle in the up position for the occupants placed near this type of opening. Indeed, this integration is often compromised by the presence of a guide rail disposed at the roof of the vehicle. It is therefore incompatible to position a holding handle at the level of the flag considering that a guide rail integrated in the flag condemns a fixing area for a

holding handle.

  Another disadvantage comes from the manufacturing cost of such a sliding door to take the set of - 't' <* '. l ew r a- --- to ------------- - {.4 v. ZievSr known features on sliding doors for vehicles of higher gauge. To overcome the constraints related to the cost of manufacture, only a grouping of several functions ensures a reduction in manufacturing cost. An object of the present invention is to provide a sliding door, for a motor vehicle, provided with at least one inner handle, comprising connecting means cooperating with guide means, the connecting means 10 are secured to the opening, the guiding means integrated into the structure of the vehicle are guide rails arranged longitudinally to the vehicle which overcomes all or some of the disadvantages of the prior art mentioned above, characterized in that at least one connecting means is a means of 15 gripping for the manual control of opening / closing

of the sliding door.

  Advantageously, the invention provides a sliding door for a motor vehicle characterized in that the gripping means is an inner handle provided with two ends and shaped so that one end cooperates with an upper guide means identifiable by a top rail arranged in the roof of the vehicle, the other end cooperates with the amount of the sliding door.

  The invention also relates to a sliding door for a motor vehicle, provided with at least one gripping means, characterized in that at least one means for unlocking the door, when the door is closed, is integrated in a gripping means.

  Another advantage relating to the invention lies in the use of a sliding door for a motor vehicle characterized in that the gripping means represented by the inner handle also performs the function of holding handle when the sliding door is in position. closed, in a locked state on the vehicle structure.

  Other peculiarities and advantages will appear at the

  reading of the description given by way of example, hereinafter

  with reference to the figures in which: - Figure 1 is an external view of a vehicle provided with a sliding door in a closed state, according to the invention - Figure 2 is an external view of a vehicle provided with the sliding door in a fully open state, according to the invention; - Figure 3 shows a side view of the sliding door in open state on the vehicle according to the invention; - Figure 4 is an enlargement of the means of FIG. 5 is an enlargement of the connecting means shown in FIG. 4, seen from the outside of the vehicle, FIG. 6 is an enlargement of the connecting means of FIG. the door on the guide means disposed in the roof of the vehicle, the sliding door being in an almost closed state,

according to the invention.

  The present invention relates to a sliding door 1 disposed on at least one of the lateral sides of a vehicle

  automobile 10, as shown in FIG.

  The size of the sliding door 1 associated with the length of the guide means ensures an opening on almost the entire space defined by two rows of seats 7a.

  and 7b, as highlighted in Figure 2.

  The application of the subject of the present invention, as described, is nonlimiting and is given by way of example for a city-type vehicle. Indeed, the sliding door 1 can also be integrated on top model vehicles of the sedan or single-body type, which have for example two or three rows of seats whose access is facilitated by the use of at least one opening,

  which can be of the sliding door type.

  The sliding door 1 is moved longitudinally to the vehicle by at least one occupant, which provides the energy necessary to provide access to the two rows of seats 7a and 7b juxtaposed. This energy is transmitted to a gripping means 2c related to the structure of the door

sliding 1.

  The following description gives details in a non-limiting way of the number of connecting means making it possible to link the

  door to the guide means. The guide means described below are three but may be more or less

fewer.

  The vehicle 10, a part of the bodywork of which is visible in FIGS. 1, 2 and 3, is composed of a door

  sliding 1 whose connecting means cooperate with the guide means constituted by a low rail 3a disposed on a spar, by a median rail 3b disposed on the structural elements of the rear fender 5 of the vehicle visible in FIG. 1, finally by an upper rail 3c disposed in a portion of the roof 4 of the vehicle.

  FIG. 3 details the device enabling the movement of the sliding door 1 to be implemented. The latter follows guide means integrated into the structure of the vehicle, which are identifiable by guide rails 3a, 3b and 3c shaped so as to respectively to accommodate one of the two ends of the connecting means 2a, 2b and 2c of

the sliding door 1.

  The particularity of the invention lies on one of the connecting means, namely the connecting arm 2c arranged in the upper part.

  Indeed, the upper arm for connecting the sliding door to the upper guide rail 3c also serves as a gripping means. The arm is shaped, by means of a molding operation, in a handle 2c oriented

  transversely to the vehicle to provide excellent grip by the hand of at least one occupant of the vehicle.

  One of the two ends of the handle 2c is provided with a sliding means, such as a system based on at least one bearing. The other end is attached to the amount of the

sliding door in a known manner.

  The use of a gripping means in the up position as shown in Figures 4 and 5, has the advantage of optimizing the operation of the opening.

  Figures 4 and 5 show the gripping means 2c disposed on a half open door. In this position of the opening 1, the handle 2c is accessible to the occupants of the seats of the second row 7b in order to continue the opening phase 15 to a fully open position, as shown in FIG. 2. The gripping means 2c is accessible to the passengers located at the front row seats 7a on a run of the sliding door 1 between the closed position visible in Figure 1 and a half-open position as shown in Figure 4. In half position the passengers in the first and second row seats have easier access to the gripping means 2c.

  It is easier to understand the interest of the invention in

  these two figures, the gripping means to be accessible to occupants located in two rows of seats.

  The transverse arrangement of the handle 2c in the up position provides the occupant holding function on the first row of seats. If the opening 1 is in a fully closed state and is locked on the vehicle structure, the curved shape of the guide rail 3c, shown in FIG. 6, makes the sliding door come into contact with a sealing element 8 that is present. on the structure of the vehicle. This figure 6 therefore underlines the transverse positioning of the

  handle 2c which also provides the handle function. Thus, the upper connecting means is a handle 2c ensuring: - the connection of the sliding door 1 in the guide rail 3c, - the gripping function to manually control the opening / closing of the opening 1, - the maintenance function for the occupant of the vehicle 1o disposed on the first row 7a of seats, when the opening

  1 is locked on the vehicle structure.

  An improvement of the handle 2c, not shown in the figures, is to add a control function of the unlocking of the opening. By means of a sensor of the type with mechanical or capacitive contact, for example, arranged on the gripping means 2c of the present invention, the occupant can control a means of unlocking the sliding door 1. Of course, this action unlocking is made active only under certain conditions, which can be for example the cutting of the contact and the positioning of the gearbox in neutral. Thus, under certain conditions the sensor arranged on the handle 2c

  controls the automatic operation of the unlocking means of the sliding door 1.

  Finally, although the invention has been described in connection with particular embodiments, it includes all the

  technical equivalents of the means described.
