Description

  An object of the present invention is a seat back tilting device for an automobile.

  In an automobile, a seat, specifically a front seat, is usually equipped with a seat back tilting device. By this tilting device, the seat can be rotated from the starting position to the position where the seat is tilted.

  The tilting of the seat is usually adjusted using a tilting device with a tilting control handle, also referred to as an operating handle or operating lever, which adjusts the seat tilting so that Fixed to a control shaft that can transmit movement to the seat pivot shaft.

  Two types of control handles are known. As shown in FIG. 1, the first control handle 1 a is attached with an opening 11 having a square or rectangular cross section, for example. The opening 11 allows the handle 1a to slide into the tilt control shaft. The return member of the handle 1a is disposed inside the opening 11 and can fix the handle 1a to the control shaft. The seal 12 prevents the handle 1a from loosening.

  As shown in FIG. 2, the second control handle 1b includes a groove 13 intended to receive the spring 14, so that the handle 1b can be fixed to the control shaft. Prevent loosening.

  The use of these two types of handles involves the use of two separate tilt control shafts, making the installation of the adjustment device complex and costly.

  The present invention proposes to remedy these drawbacks.

  Specifically, the present invention proposes a seat back tilting device having a tilt control shaft adapted to both types of handles.

  The object of the present invention is therefore a seat back tilting device comprising a tilt control handle that can be selected from a first control handle and a second control handle, and a tilt control shaft to which the control handle is mounted.

In the apparatus according to the present invention, the control shaft comprises:
An area for receiving a first return member associated with the first control handle;
A region for receiving a second return member associated with the second control handle, and a region for transmitting a force from the first control handle and a force from the second control handle.

  The region for receiving the first return member and the region for receiving the second return member can be separated.

  The region for receiving the first return member and the region for receiving the second return member may coincide.

  The region for transmitting the force from the first control handle and the force from the second control handle may have a rectangular or square cross section.

  The control shaft can also include a stop for longitudinally blocking the control handle.

  The control shaft may be equipped with a polarization system.

  The polarization system can be realized by using different dimensions for the surface of the control shaft.

  The polarization system can be realized by ribs on the control shaft intended to receive the fingers of the control handle.

  The return member associated with the first control handle may form an integral part of the first control handle with a seal, and the return member associated with the second control handle comprises the It may be a member that is separate from the second control handle.

  The object of the invention is furthermore the use of the device described above for tilting the seat back of a car seat.

The object of the present invention is also
A tilting kit comprising the tilting device just described, equipped with a first tilting control device, and the tilting device just explained, equipped with a second tilting control device.

  Further features and advantages of the present invention will become more apparent from reading the following description, given by way of non-limiting example, with reference to the accompanying drawings.

FIG. 1 (already described) shows a first type of control handle that can be used in a device according to the invention. FIG. 2 (already described) shows a second type of control handle that can be used in the device according to the invention. FIG. 3 shows part of the apparatus of the present invention according to the first embodiment. FIG. 4 shows part of the apparatus of the present invention according to a second embodiment. FIG. 5 shows part of the apparatus of the present invention according to a third embodiment. FIG. 6 shows part of the apparatus of the present invention according to a fourth embodiment. 2 is a cross-sectional view of two devices according to the present invention.

  As shown in FIG. 3, the tilt control shaft 2 according to the present invention has a region 21 for receiving the return member of the first control handle 1a shown in FIG. 1, and the second control handle 1b shown in FIG. It has a region 22 for receiving the return member, a force transmission region 23, and a stop 24 intended to block the control handles 1a, 1b in the longitudinal direction.

  The return members 14 and 15 are intended to secure the control handles 1b and 1a to the tilt control shaft 2, the first return member 15 being associated with the first control handle 1a and the first control handle 1a. The second return member 14 is associated with the second control handle 1b and is intended to fix the second control handle 1b to the tilt control shaft 2. And

  The control shaft 2 can be generally a rectangular parallelepiped having a rectangular or square cross section.

  The receiving area 21 may take, for example, a dish shape, specifically a U-shaped or V-shaped recessed shape. The receiving area 22 can take the form of a rib. The force transmission area 23 is an area intended to transmit a force from each control handle 1a, 1b to the control shaft 2.

  The apparatus also comprises a polarization system for preventing the handles 1a, 1b from being mounted in the wrong angular orientation. The polarization system can be realized by using different dimensions for the surface of the control shaft 2. The polarization system can also be realized by a region 25 projecting from one of the faces of the control shaft 22, which can have, for example, a circular outer surface. The protruding region 25 also defines a stop 24 that translates along the control shaft 2 relative to the control handles 1a, 1b.

  In the second embodiment, as shown in FIG. 4 where the same elements as in FIG. 3 have the same reference numbers, the control shaft 2 is a single unit for receiving the return members of both control handles 1a, 1b. Regions 21 and 22. The receiving areas 21 and 22 are ribs that can receive both return members for the handles 1a and 1b. The control shaft 2 also comprises a two-part force transmission area 23 on either side of the areas 21 and 22 for receiving the return member. The control shaft 2 also comprises a polarization system realized by the use of different dimensions for the surface of the control shaft 2.

  A third embodiment shown in FIG. 5 in which the same elements as those in FIG. 4 have the same reference numbers is a larger defined stop 24 in which the control shaft 2 is arranged in the extension of the force transmission area 23. It is similar to 2nd Embodiment except providing.

  Finally, in a fourth embodiment shown in FIG. 6, the control shaft 2 is provided with ribs 26 intended to receive the fingers of the control handles 1a, 1b and constitute a polarization system. This polarization system differs from the first three embodiments in which the polarization system is realized with different dimensions of the face of the control shaft 2.

  The lower part of FIG. 7 shows the first control handle 1 a installed on the control shaft 2, whereas the upper part shows the second control handle 1 b installed on the control shaft 2.

  The first control handle 1 a includes a return member 15 that exerts an upward thrust in the direction of the control shaft 2. The seal 12 prevents the handle 1a from loosening.

  In the case of the second control handle 1b, the return member 14 is not included in the control handle 1b. The return member 14 can fix the handle 1b to the control shaft 2 and prevent the handle 1b from loosening.

  The present invention also relates to a tilt kit comprising two tilt devices, one of which is equipped with a first tilt control device 1a and the other of which is equipped with a second tilt control device 1b, Thus, the tilt kit comprises two tilt control devices 1a, 1b and at least one control shaft 2.

  It should also be noted that the device according to the invention can also be used in other types of rotation control devices.
