Abstract
Description
Title of the invention: Method for securing eyeglasses in a motor vehicle, and associated eyeglasses
[0001] The invention relates to the safety of occupants of motor vehicles, when these occupants wear glasses including jaws, particularly practical for holding the glasses securely when worn by these occupants.
[0002] In the event of a collision with the vehicle, the face may violently strike a part of the vehicle, in particular a safety airbag, and the glasses worn by the occupants may then cause head injuries to the occupants.
[0003] To remedy this drawback, the invention relates to a securing method, implemented by (in other words: in) glasses worn by a person located in a motor vehicle, the glasses comprising two rims, connected by a bridge, each surrounding a (transparent) lens which may be, for example, made of transparent polycarbonate or an organic lens, and two temples, (the glasses being shaped so that each of the two temples is located between an ear and the skull of the person when the glasses are worn by the person,) each of the two temples being connected: • By a hinge, at one of the two circles, at a first end of each of the two branches, and • By a mechanical connection, to a sleeve, at a second end of each of the two branches, opposite the first end, the process comprising the following steps: • Removal of a link (whether part of, for example, the mechanical linkage, or not) to make the sleeve mobile relative to each of the two arms so that each of the two arms slides against an ear (in other words: between an ear and a skull of the person) of the person and the glasses move away (in other words: eject) from a face of the person, if a head of the person (in other words: if the person) moves in a direction from the second end to the first end (in other words: moves in a direction from the back of the head to the face of the person,or moves in a direction from the ear to the part of the eye of the person closest to the ear) undergoing a deceleration greater than a threshold (in other words: sufficient deceleration) (in the direction) (in other words: such that the glasses are ejected from the head of, the person if their head is subjected to sufficient deceleration towards the front of the vehicle), and / or • maintaining the connection to keep (in other words: to make) the sleeve fixed and inclined relative to each of the two arms so as to prevent each of the two arms from sliding against the ear (in other words: between an ear and a skull of the person) (in other words; so as to prevent a translation of the glasses in a direction, or so as to prevent the sleeve from coming against the ear, or so as to prevent the glasses from being ejected from the head of the person), otherwise (that is to say if the head of the person does not move in the direction or does not undergo a deceleration greater than a threshold (in the direction)).
[0004] In other words, the invention relates to a securing method, implemented in glasses worn by a person located in a vehicle, the glasses comprising two arms, each of the two arms being connected to a sleeve, the method comprising the following steps: • Removal of a mechanical link (whether or not it is part of a mechanical link between the sleeve and each of the two arms) to make the sleeve movable relative to each of the two arms so that the glasses eject from the person's head (200), if the head (220) is subjected to sufficient deceleration towards the front of the vehicle, and / or • Maintaining the link to make the sleeve fixed and inclined relative to each of the two arms so as to prevent the glasses from being ejected otherwise.
[0005] Thanks to the invention, the glasses move away or are ejected from the head, when the person is restrained by a seat belt, following a collision between the motor vehicle and an object, before the head encounters a part of the vehicle, for example, a safety cushion.
[0006] Of course, the link maintenance step can take place before the link removal step, or after the link removal step, for example, if the link is restored after the link removal step and before the link maintenance step.
[0007] According to one embodiment, the mechanical link comprises an axis, and the removal of the link makes the sleeve mobile in rotation (relative to each of the two branches) around the axis, while remaining attached to said each of the two branches by the axis.
[0008] Alternatively, removing the link completely detaches the sleeve from each of the two branches.
[0009] According to one embodiment, the link comprises a finger and a cavity of the sleeve, the removal of the link comprising a step of exiting the finger from the cavity of the sleeve, the maintenance of the link comprising maintaining the finger in the cavity of the sleeve.
[0010] Alternatively, the link may be a piece, for example of fabric or plastic, the removal of the link including a step of tearing the piece, the retention of the link including a holding of the piece.
[0011] According to one embodiment, the mechanical link comprises a tunnel and a mass including the finger, the step of exiting the finger from the cavity of the sleeve includes a displacement of the mass resulting from the deceleration, inside the tunnel (in other words; in the tunnel), so as to make the finger exit the cavity, and the retention of the finger in the cavity of the sleeve includes a retention of the mass by an elastic element (for example, a spring) so that the finger remains (in other words: is held) in the cavity.
[0012] Of course, the mass (in particular the weight of the mass) and the elastic element (for example the wire diameter, the wire material, the number of turns, the diameter, and / or the pitch, in the case of a spring) are chosen for this purpose.
[0013] Alternatively, the finger can be held in or removed from the cavity by a mechanism selected from: • A motor and a gear, or • An electromagnet, or • A pyrotechnic charge.
[0014] The same applies to the suppression or maintenance of the link, in general, which can be implemented by one of these mechanisms or by a mass.
[0015] According to one embodiment, the process further comprises the following steps: • Receiving patterns (in other words, data representing patterns) from the motor vehicle, • Display of patterns on (and / or in) the glasses.
[0016] The glasses can therefore be augmented reality glasses. These could be, for example, the glasses marketed under the brand name "light" by the company "XREAL", or using the technology marketed by the company "LUMUS".
[0017] Alternatively, the glasses are prescription glasses without electronic components.
[0018] The invention also relates to glasses (or a motor vehicle) configured to implement the steps of the process according to the invention, as well as a motor vehicle comprising the glasses.
[0019] The characteristics and advantages of the glasses and the motor vehicle are identical to those of the method according to the invention (without it being necessary to repeat them here).
[0020] When glasses, a motor vehicle, or another element is "configured to" (or "suitable to" or "fitted to") perform or implement a step or operation, this implies, for example, that the element includes means for performing the step or operation. These means preferably include mechanical means. They may also include electronic means, for example, a computer program, data in memory, specialized electronic circuits, wired or wireless connections, a microprocessor, and / or a microcontroller.
[0021] Other features and advantages of the present invention will become more apparent upon reading the following detailed description, which includes embodiments of the invention given by way of non-limiting examples and illustrated by the accompanying drawings, in which: • [Fig. 1] represents eyeglasses and a motor vehicle according to one embodiment of the invention, • [Fig.2] and [Fig.3] the glasses of [Fig.1], worn by a person during steps of the process shown [Fig.4]. • [Fig. 4] represents an implementation of the process according to the invention, according to a example of realization, by the glasses of [Fig.1].
[0022] Detailed description of an example embodiment of the invention, with reference to figures 1 to 4.
[0023] In [Fig. 1] to 3, certain elements are, of course, seen through transparency. For example, [Fig. 2], the mass 1411 is seen through transparency of the ear 211 and the casing of the mechanical linkage 141.
[0024] Fig. 1 represents, in a vehicle (automobile) 1000 driven by a person 200 wearing glasses 100.
[0025] Figures 2 and 3 show, at various stages of the process, a close-up of the glasses 100, [Fig. 1], as worn by the person 200 in the vehicle 1000, in lateral view. Only one side of the glasses is shown in Figures 1 and 2, the opposite side being identical, particularly during the implementation of the process described in [Fig. 4].
[0026] The glasses 100 comprise two circles 111, 112, connected by a bridge, and each surrounding a transparent lens which can be, for example, made of transparent polycarbonate or an organic lens, and two temples 131, 132.
[0027] The 100 glasses are, for example, augmented reality glasses, well known to the person skilled in the art.
[0028] They can, for example: • Receive patterns (in other words, data representing patterns) from motor vehicle 1000, • Display the patterns on the glasses.
[0029] As shown [Fig.1], when the glasses 100 are worn by the person 200, the arm 131 is located between an ear 211 and a skull of the person 200, and the arm 132 is located between an ear 212 and a skull of the person 200.
[0030] As shown in [Fig.2], the branch 131 is connected by the hinge 121, to the circle 111 at the end 1311 of the branch 131. Also, the branch 132 is connected, by the hinge 122, to the circle 112.
[0031] The branch 131 is connected to the sleeve 151, by a mechanical link 141, at the end 1312 of the branch 131. Also, the branch 132 is connected, by a mechanical link 142 to the sleeve 152.
[0032] With reference to [Fig.4], at step S00, the vehicle 1000 travels normally, without hindrance, in a direction si and a direction dl going from the second end 1312 to the first end 1311.
[0033] The head 220 of the person 200 does not undergo significant deceleration during this normal circulation. Consequently, as shown [Fig. 2], the spring 1412 maintains the mass 1411 so that the finger 1413 remains in the cavity 1511, which keeps the sleeve 151 fixed and inclined relative to the arm 131. The sleeve 151 thus prevents the arm 131 from sliding against the ear 211 towards the front of the vehicle.
[0034] At step S10, the vehicle 1000 collides with an obstacle 300. The person 200, and in particular his head 220, continues his movement in the direction si and a direction dl subjected to restraint by a seat belt, generating a deceleration sufficient (i.e.: greater than a threshold) to move the mass 1411 inside the tunnel 1414 of the mechanical link 141 and to make the finger 1413 come out of the cavity 1511 of the sleeve 151.
[0035] The sleeve 151 then becomes mobile in rotation around the axis al, while remaining fixed to the branch 131 (and to the mechanical link 141) via the axis al.
[0036] These steps occur simultaneously for the arm 132, the sleeve 152 and the mechanical link 142, which are identical respectively to the arm 131, the sleeve 152 and the link 141, so that, at step S20, as shown [Fig.3], the two arms 131 and 132 slide respectively against the ears 211 and 212, and the glasses 100 move away (in other words: eject) from the face 221 of the person 200, thus limiting the risks of injury to the person 200 caused by the glasses 100.
[0037] According to one embodiment, the movement of the mass 1411, in step S10, exerts a tension on the axis al which breaks the axis al and completely detaches the sleeve 151 from the arm 131 and the mechanical linkage 141. In this embodiment, the axis al could be a nylon thread, for example. The mass could also include a blade for cutting the axis al.
