• the adjustable lateral headrest 100 is mounted on a child seat 110 for cars.
• the headrest 100 is installed on the child seat 110 by means of one or two vertical slots 111 formed in the shoulders 112 of the seat 110 and into which, or which, a screw 113 or threaded rod will be introduced. and will serve to block the headrest 100 in an ideal position from a height point of view by means of a thumb wheel 114 which is screwed onto it, on the outside of the shoulder, thanks to its nut 115.
• the inclination of the body 116 of the headrest 100 relative to the horizontal, in a plane substantially parallel to the backrest 120 of the seat 110, is here fixed by the orientation of the screw 113 relative to this body 116.
• This screw 113 is, on the other hand, pivotally mounted (double arrow A) on the body 116 of the headrest 100 by means of pins received in hollow housings (not shown in the drawings for the sake of clarity) arranged in the inside a spherical part 117 of a core 118 of the body 116, with a view to being able to move the back 120 of the seat 110 towards or away from it the free end 119 of the body 116, by rotation about a substantially vertical axis and s 'extending substantially parallel to the back 120 (also not shown in the drawings for the sake of clarity).
• the spherical part 117 cooperates, in this regard, with the associated shoulder 112, after tightening the nut 115, in order to fix the position of the body 116 of the headrest 100 optimally in the chosen position.
• this spherical part 117 can be replaced by a simple convex shape.
• the screw 113 can also be mounted on this spherical part 117 by means of a ball joint in order to offer possibilities for adjusting the body 116 around three axes forming an orthonormal reference, namely an adjustment in inclination relative to the 'horizontal, in a plane substantially parallel to the backrest 120 (around a substantially horizontal axis and extending substantially perpendicular to the part of the backrest 120 receiving the passenger's back), an adjustment in approach / away from the free end 119 from file 120 (around a substantially vertical axis and extending substantially parallel to the back 120) and an adjustment with respect to the horizontal, in a plane extending substantially perpendicular to the back 120 (around an axis substantially horizontal and s' extending substantially parallel to the part of the backrest 120 receiving the back of the passenger).
• This latter adjustment can be used to position the body 116 of the headrest 100 in order to prevent movement of the head tending to move it away
• a part 121 of the core 118 is slightly concave and is wrapped in a comfort part 122 which has a thicker zone 123 constituting an anti-tilt system from the head towards the before during the sleep of the child, during a brake application for example.
• This zone is that which is opposite the back 120 of the seat unlike that thinner 124 which is adjacent to the back.
• the thicker zone 123 could, for example, be formed by a bead, a pronounced rounded or concave shape or be replaced by a wall disposed generally transversely to the comfort part 122.
• a scalloped portion 125 provided at the free end of the body of the headrest 100 here allows it to adapt to the child's neck. Its thickness, its flexibility, its softness constitute a guarantee of preservation of the physical integrity of the child even in the event of a side impact suffered by the vehicle in which the seat is installed.
• the assembly requires that the screw be inclined during manufacture either towards the thicker zone 123 or towards the thinner zone 124, a straight headrest and a left head.
• This headrest 100 is removable by simply unscrewing the thumb wheel 114, although when installed, the child can keep his head straight and uncomfortable.
• the headrest 200 for aircraft seat 210 uses a lateral support 211 which allows it to be adjusted in height (double arrow B), in inclination up and down (double arrow C) and in rotation of approach / distance (double arrow D) relative to the backrest 212 of the seat 210.
• This support 211 is fixed to the structure of the seat 210 either during manufacture or after, depending on the technical possibilities.
• the headrest 200 is removable, so that it can easily be removed when the passenger does not wish to use it.
• the support 211 comprises a tubular piece 213 mounted on a base 214 fixed to a lateral edge of the backrest 212 of the seat or airplane chair.
• the tubular part 213 or tube is equipped with a brake 215 which can be replaced by a ratchet system.

• This bar portion 217 is long enough to offer a latitude for adjusting the height of the headrest 200 according to the size of the user. This length can also allow kinematics for storing the headrest in a housing 218 formed at the top of the backrest 212, as shown in the variant of FIG. 9.

• the present invention thus dramatically improves comfort for passengers, especially those on long distance flights. It is in particular possible to adjust (see FIG. 6) the body 221 of the headrest around a substantially horizontal axis 232 and extending substantially perpendicular to the backrest 212 of the seat 210 (adjustment in inclination up or down relative to horizontally, in a plane substantially parallel to the backrest 212) and around a substantially vertical axis 233 and extending substantially parallel to a lateral edge 234 of this backrest 212 (to bring the free end towards or away from the backrest 212 235 of the body 221 by rotation in a plane substantially perpendicular to the backrest 212.
• the body 221 of the headrest is, moreover, provided with a notched part 225 for receiving the user's neck and a thickening 226 on the side opposite that adjacent to the backrest 212, preventing any movement of the tending head away from this file 212.
• An additional adjustment of the position of the headrest 200 can be added, either by the addition of a pivoting articulation 227 with ratchet 228 ratchet 228 between the tube 213 and the base 214 ( Figures 7a and 7b), or by the addition of a pivot at the elbow of the bent bar ( Figure 8) which then becomes two separate parts, a vertical 229 and a horizontal 203, the two being connected by two friction parts 231 and 232 tight and fixed together after adjustment by a screw brake 233.
