Description

DEVICE FORMING HEADREST SIDE

VEHICLE

[1] The invention relates to a device forming a side head rest for vehicle mounted mobile on a side inner wall of the vehicle.

[2] Motor vehicles are generally equipped with headrest provided in the extension of the seat backrest. This type of headrest has a function related to passenger safety because it helps retain the head of the latter when the vehicle is impacted in an accident. This type of headrest also has a function related to passenger comfort as it allows the latter to lay his head there. Nevertheless, the position in which there is a passenger who wants to lay his head back is not the most comfortable. A more natural and comfortable resting position is to lay his head on the side. But on the side of a vehicle is the side window which provides a cold rest, hard surface due to the material. In addition, with respect to the position of the passenger, this surface is relatively remote from the passenger's trunk and does not offer an ergonomic rest position.

[3] According to a first prior art, there are headrests fixed on the seat and movable between a position in the extension of the backrest and a position on the side. But in this case, when the headrest is disposed on the side, the function related to the safety of the passenger is no longer ensured. Conversely, if you want to keep the headrest in the extension of the seat, the function related to the comfort and rest of the passenger can not be assured.

[4] According to a second prior art, there are headrests having a portion adapted to extend laterally beyond the headrest slidably so as to allow a passenger to rest his head on it the side. This complicates the embodiment of the headrest involving adding to the headrest at least one additional portion for lateral support as well as a retraction mechanism and sliding deployment comprising e.g. slides. In addition, the side portion, when extended, is no longer held by one of its ends: it is then weakened and lack of stability. Therefore, when extended and the passenger rests his head on the side portion, it may move or become detached from the headrest.

[5] Finally, according to a third prior art, there are lateral head restraints, that along the side of the vehicle is to say formed. These headrests may be movable between a retracted position against the rear quarter of the vehicle and a deployed position projecting from the rear quarter. However, in the deployed position, they remain at the rear side wall of the vehicle compartment and do not come donations not offer a resting surface at the side window. These lateral headrests provide support that is on the side and back at the quarter, this forces the passenger to have his head back offering less comfort than when the head rests solely on the side. [6] The object of the present invention is to provide a device forming a single lateral headrest and compact.

[7] For this purpose, the invention relates to device forming side headrest for a vehicle comprising a movably mounted headrest body on a side inner wall of the vehicle between a stowed position and a deployed position offset along the wall characterized in that the headrest body is pivotable about an axis orthogonal to the inner wall such that an edge thereof describes a circular arc on the vehicle wall. [8] Advantageously, the axis is also orthogonal to the mean plane of the headrest.

[9] Preferably, the headrest body is movable in translation on the axis so as to move away from the inner wall to deploy and to get closer to retract.

[10] The headrest in the deployed position are advantageously located next to the side window. [11] The axis is preferably located at an edge of the headrest.

[12] Advantageously, the device comprises an arm fixed to the headrest and a tube fixed to the inner wall adapted to cooperate by interlocking to allow pivoting of the headrest around the axis with respect to the inner wall.

[13] Preferably, the tube is hollow and comprises a guide path in which can pass a lug formed on the arm so as to guide the headrest.

[14] The guide path advantageously comprises at its ends stops adapted to immobilize the head rest in one or the other of its positions between its ends and a central portion adapted to move away or closer to headrest of the inner wall.

[15] The central portion is preferably straight. [16] The tube advantageously comprises a spring whose force has a direction parallel to the axis.

[17] Other features and advantages become apparent from the description which is given below, for information and in no way restrictive, with reference to the accompanying drawings, wherein:

- Figure 1 is a perspective view of the passenger compartment of a vehicle with a rear seat with a lateral headrest in the retracted position;

- Figure 2 is a perspective view of the passenger compartment of a vehicle with a rear seat with a lateral headrest in the deployed position; - Figure 3 is a top sectional view of the support of the headrest;

- Figure 4 is a front sectional view of the headrest support; - Figure 5 is a perspective view of the support of the headrest;

- Figure 6 is a top sectional view of the headrest;

- Figure 7 is a front sectional view of the headrest tube.

[18] Figure 1 shows a part of the passenger compartment 1 of a motor vehicle in which there is a rear seat 3.

[19] The seat back 3 comprises a backrest 5 and a first headrest 7 in the extension of the backrest 5. [20] The interior of the vehicle 1 also includes an inner side wall 9 on the side of the seat 3. This wall 9 includes the rear quarter panel 11, the rear door 13 provided with a window 15 and the center pillar 17. the rear quarter panel 11 comprises a second headrest 19 which is placed laterally relative to the first headrest 7.

[21] The side headrest 19 is fixed to the rear quarter panel 11 and movable in rotation relative to the latter between two positions. A first retracted position E against quarter 11 of the panel is shown in Figure 1. A second deployed position D wherein the side headrest 19 is opposite the window 15 of the door 13 is illustrated in Figure 2.

[22] The assembly constituted by the second headrest and side members connecting the headrest 19 to the inner wall 9 of the vehicle is a device forming a side head rest. [23] The device forming side headrest comprises, on the one hand, the support 21 of the headrest visible in Figures 3, 4 and 5 and, on the other hand, the body 23 of the appui- head visible in Figure 6. the support 21 is fixed on the wall 9. the body 23 of the headrest is pivotable and translatable relative to the support 21.

[24] According to Figure 3, the support 21 of the headrest comprises a plate 25 on which a hollow tube 27 is attached.

[25] The plate 25 has a substantially rectangular shape and may be made of metal or plastic material. The plate 25 is intended to be fixed on the vehicle body by screwing for example. According to FIG 4, the hole 25 comprises two plate 31. In Figure 3, two screws 29 pass through the plate to cooperate with the holes 31 of the plate 25 and with a non-visible thread in the figures formed in the vehicle body .

[26] According to FIGS 4 and 5, the tube 27 has a circular section. The material used may be the same as used for the plate 25. The tube 27 is secured at one of its ends to the plate 25. At its free end, the tube 27 comprises a flange 33 wider than the thickness of its wall. 35 of the tube wall 27 has a thickness sufficient to allow to dig a guide path 37.

[27] The guide path 37 is widened on the inner surface 39 of tube 27. According to Figure 5, the guide track 37 includes two stops 41 and 43 at its ends and a central portion 45.

[28] The path formed at the ends of the guide path 37 is substantially orthogonal to the path formed at the central portion 45. This trajectory is particularly visible in figure 4.

[29] The central portion 45 is shown in Figures 3 and 5 as being rectilinear. This portion may also be curved about the height of the tube 27 and be helical. [30] The attachment of the tube 27 of the plate may be performed by welding for example. The tube 27 may also have been molded together with the plate 25 and thus be integral with the latter. [31] According to Figure 3, the support 21 of the headrest further comprises a spring 47. The spring 47 is fixed to the plate 25 and disposed within the tube 27. The biasing force s' applied perpendicularly to the plane of the plate 25. the spring 47 is preferably a compression spring. [32] According to Figure 6, the body 23 of the headrest comprises an arm 49 and a cushion 51. The arm 49 is fixed perpendicularly to the median plane of the pad 51. It can be secured undetachably example by gluing or welding or detachably for instance by clipping. According to Figures 1 and 2, the arm 49 is attached near one edge of the cushion 51 of headrest. The cushion 51 having a rectangular shape, the arm 49 is attached near a short side of the cushion. This allows to move from a retracted position retracted E at the rear quarter panel 11 to an advanced D deployed position facing the window 15 of the vehicle door. In this way, the side headrest does not bother the passenger when in the retracted position E and is in contrast to the level of the passenger's head in the deployed position D. The passenger then has only tilting his head to the side when he wants to rest.

[33] The cushion 51 of headrest shown in Figures has a parallelogram shape, preferably rectangular. The cushion may also have other suitable shapes such as oval, for example. [34] The cushion 51 of headrest includes a rigid base 53 which may be made of metal or plastic. The base 53 is covered with a flexible layer 55 of foam for comfort. The foam layer is covered with a coating 57 such as fabric or leather according to the finishing coating selected in the vehicle. [35] According to FIG 7, the arm 49 has a circular section. The arm diameter is substantially smaller than the inside diameter of the tube 27 to be inserted therein. The arm 49 is fixed at one of its ends to the base of the headrest, its other end being free and intended to be introduced into the hollow tube 27 of the support 21 so as to allow cooperation with pivoting and translation of the body headrest and headrest support.

[36] The arm 49 comprises a lug 59 formed on its surface, according to Figure 7, this lug 59 is stationary on the arm 49 is situated on the side of the free end of the arm.

[37] When the arm 49 is engaged in the tube 27, the lug 59 is in the guideway 37. The lug 59 has an appropriate length which allows the arm 49 not separating from the tube 27 when the arm slides in the tube. The arm 49 is pivotable according to the arrow F1 in the tube about its axis AA '(figure 6). The arm can also translate according to the arrow F2 in the tube 27 along its axis AA '.

[38] According to an embodiment not shown, the pin could also be retractable. In this case, it might be possible to dispense with the central portion of the guide path, the pin being retracted when the arm is in translation. The pin would then projecting stops at the level of the ends of the guide path. [39] The body 23 of the headrest 61 also comprises a flexible shim made of rubber for example. This washer is used to compensate plays and to promote a better bearing surface between the washer 61 of the arm 49 and the flange 33 of the tube 27, that is to say, more generally between the body 23 and the support 21 of head support.

[40] We will now describe the method of retracting the side headrest according to the embodiment shown in Figs. [41] The lateral headrest can be moved from a retracted position E to an extended position D and vice versa.

[42] In the retracted position E, the cushion 51 of headrest is located against the surface of the wall 9 of the inner rear quarter panel 11 (Figure 1). The arm 49 of the body 23 of headrest is pushed to the maximum in the tube 27 of the support 21 of headrest. For this purpose, the pin 59 of arm 49 is located at the end 41 of the guide path 37, into abutment.

[43] When the user wishes to deploy its lateral headrest, it takes the edge of the cushion 51 farthest headrest him towards the glass 15 of the door so as to rotate it around the axis AA 'of the arm 49 in the direction of clockwise. The cushion 51 of headrest then scans the surface of the inner wall 9 of the vehicle and performs approximately a quarter turn. The lug 59 passes through a first stop 41 and enters the central portion 45 of the guide path 37. The arm 49 has performed a quarter turn in the tube about its axis in the direction of clockwise. The headrest is then approximately in an intermediate position at 90 degrees from the retracted position E.

[44] The cushion 51 of headrest automatically moves away from the inner wall 9 by a distance equal to the length of the central portion 45 of the guide path 37. The arm 49 of the headrest slide along the tube 27 of the support 23. Under the impulse of spring 47, the pin 59 passes in a straight line along the central portion 45 until the beginning of the second stop 43.

[45] Finally, the user again rotates the headrest cushion of a quarter of a turn in the direction of counterclockwise until it is in the extension of the appui- head in the retracted position E. The headrest is then in its deployed position D (Figure 2). The arm 49 of the headrest is rotated a quarter turn into the tube 27 of the support 23 about the axis AA '. The lug 59 passes through the second end 43 of the guide path 37 until the end of the latter. The headrest is then locked in the deployed position D.

[46] To bring the headrest in its retracted position E, the user performs the same steps as above in a reverse order. Thus, it turns the cushion 51 of headrest a quarter turn in the counterclockwise direction of a watch. The user then presses the headrest so as to exert pressure in the opposite direction of the force exerted by the spring 47 and towards the inner wall 9. The arm 49 then slides in the tube 27 and the lug 59 passes through the central portion 45 of the guide path 37. Finally, the user again rotates the headrest to a quarter turn in the opposite direction of clockwise until the edges long the headrest cushion can be found horizontally, and the headrest is in its retracted position E.

[47] In an embodiment not shown, the headrest may also be in a different position when retracted that position in which its long edges are horizontal. The headrest may for example be in a position in which its long edges are vertical. In this case, it is preferable that the headrest is attached to the wall closest to the window so that in the deployed position, the headrest is opposite the glass. It is then necessary to adapt the layout of the guide path to the new kinematics.

[48] ​​According to another embodiment not shown, the guide path can have other shapes. For example, in the aforementioned case in which the pin is retractable, the guide path is not continuous: in fact, in this case the central portion is not ground, the guide path comprises only stops at its ends.
