Definitions
- the present invention relates to an adjustable lateral headrest which allows a person, child or adult, seated in a seat, especially those intended for means of transport, such as an airplane, a car, a train, etc., to rest their head. on your side and sleep avoiding any muscle or neck trauma to the neck. So far, passengers of economy class aircraft or children sitting in their child seat installed in an automobile, among others, see their head going excessively to the side or forward when they fall asleep. which can cause sleep problems, cause trauma to the neck, or even amplify the consequences of a shock during a collision between two cars, especially if the child is caught in sleep and his head does not have no support at this time.
- the lateral head rests known to date such as that described for example in patent US-A-2,306,334 do not make it possible to remedy these drawbacks.
- the present invention generally relates to a provision which makes it possible to overcome these drawbacks in a simple and safe manner and which also leads to other advantages.
- a lateral headrest for a seat in particular a means of transport, comprising a headrest body adapted to support the head of the person seated in the seat and means for fixing, in particular of removably, the headrest body to the seat back, characterized in that it includes means for preventing a displacement of the head of the person tending to move it away from the seat backrest, and in that the fixing means are designed to mount the headrest body movable in translation in front of the part of the backrest against which s 'support the person's back, face or side thereof, whereby the headrest body is adjustable in height over at least part of the height of said part of the backrest.
- the headrest according to the invention thus makes it possible to remedy these drawbacks by keeping the passenger's head optimally and by providing it with great sleeping comfort.
- it can adapt to existing seats or be integrated into the structure of seats designed from the outset to receive it.
- It preferably comprises a headrest part benefiting from an inclination and rotation adjustment which makes it possible to adjust it with precision to the user's taste, and a system for fixing to the seat allowing the headrest to slide along the backrest seat, to be able to adapt precisely to the size of the user.
- the headrest is either removable or permanently fixed to the seat structure.
- a place on or in the seat structure can allow it to be stored when it is not in the active position.
- the headrest itself is preferably characterized mainly by a concave shape of the part where the head rests, by a rounded notch in the part which receives the user's neck, and by an extra thickness or a shape raised in the part which is on the side opposite the seat back, to constitute an anti-tilting system of the head forward when the user is sleeping.
- the headrest can be installed on the left or on the right of the seat, sometimes with the choice for the user to install it on the side he prefers.
- the headrest can be installed on the left or on the right of the seat, sometimes with the choice for the user to install it on the side he prefers.
- the fixing means and the headrest body comprise complementary means for adjusting the inclination of the headrest body by pivoting about a substantially horizontal axis and extending substantially perpendicular to the part of the seat back against which comes to support the person's back;
- the fixing means and the headrest body comprise complementary means for adjusting the position of the headrest body by rotation about a substantially vertical axis and extending substantially parallel to said part of the seat back against which comes to rest the back of the person or a side of this file;
- the fixing means comprise means for adjusting the position of the headrest body by rotation about a substantially horizontal axis and extending substantially perpendicular to a side of the seat back;
- the fixing means and the headrest body comprise complementary means for adjusting the inclination of the headrest body by pivoting about a substantially horizontal axis and extending substantially parallel to the part of the backrest against which s '' support the person's back, in front of the person;
- the headrest body has a conformation, in particular an additional thickness, capable of preventing said displacement
- the fixing means are designed so as to be able to pass the headrest body from its active position to a retracted position;
- the fixing means comprise means for coupling the headrest body to the bars of a headrest of a car seat backrest, in a removable manner; and - the headrest body has a notch at its free end, designed to hug the person's neck.

- 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.
- a bar bent at 90 ° 216 is threaded into the tube 213, by a part 217 having a notch making it possible to optimally fix the bar 216 in the chosen position thanks to the brake 215 or to the pawl which can replace it.
- 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 bar 216 can be reversed to lower the headrest more (FIG. 6).
- the part 219 of the bar 216 which is located after the bend has a section 220 with longitudinal grooves. It sinks inside the body 221 of the headrest 200 which itself has a tubular part 222 (FIG. 5) to receive the bar.
- This tubular part 222 is embedded in a hard part 223 of the headrest, FIG. 5.
- It is fitted with a ratchet or a thumbwheel brake 224 accessible under the body 221.
- the brake 224 or ratchet is introduced into the longitudinal grooves of the part 219 of the bar 216.
- the support part 217 of this bar slides and turns in the tube 213 (double arrow D).
- the brake 215 or the pawl is introduced into the notches of this part 217 of the bar.
- the body 221 of the headrest is traversed right through by the tubular part 222, so that it can be used to the left or to the right of the user, provided of course that the base 214 can be fixed on both sides of seat 210.
- 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.
- the tube 213 fixed to the chair can be replaced by another known type of support.
- the part which connects the body 221 of the headrest to this tube can be replaced by another form of articulation.
- all the locking and pivoting systems which make it possible to adjust the headrest can be replaced by equivalent known parts and systems.
- the very shape of the body 221 of the headrest can be different from that illustrated, provided that it allows the user to put his head down and to prevent a displacement of the latter tending to move it away from the backrest 212 of the seat 210.
- the body of the headrest 300 and its support 301 are slidably mounted on the front of the backrest 302 of an airplane chair 303 thanks to a system of sliding assembly, for example of the rack type, located in the front part of this backrest 302.
- This system also allows the headrest 300 to be housed under the armrest 304 of the chair 303, inside a housing 305 provided in the seat 306 of this chair 303.
- the location of the headrest 300 and its sliding mounting system may be different provided that it allows the headrest 300 to be adjusted in height, along the backrest 302.
- the headrest 400 can be slidably mounted on the backrest 401 of an airplane chair 402 by means of a sliding mounting system 403, for example of the rack type, incorporated in the side 404 of the backrest 401.
- An articulation 405 is also present for the adjustment in rotation (approximation / distance of the free end of the body of the headrest 400 relative to the backrest 401).
- the headrest 500 is pivotally mounted on a cylindrical rod 501, itself slidingly mounted on a support bar 502 bent at 90 °.
- the headrest is mounted on the original headrest bars of the seat. It is therefore adaptable to all seats equipped with headrests supported by bars and is easily removable when the child is not using it, although it does not interfere with the normal sitting position, head straight.
- the headrest 600 includes a mechanism 601 for fixing to the headrest bars 602.
- This mechanism 601 has two parts 603 each disposed on each side of the bars and connected by a clamping screw 604 ( Figure 17).
- the two parts 603 are rubberized at the level of contact with the bars 602, to prevent any slipping and any degradation of these bars.
- One of the two parts 603 comprises a hollow tubular part 605 of square section in which slides a bar 606 of lower section which allows sliding the lateral adjustment of the headrest 600.
- This bar 606 is locked by a screw brake 607 once the lateral adjustment has been made.
- the bar 606 also has a slot (not visible in the figures
- this support 608 adapts to the width of the backrest 609 of the seat 610.
