Description

BRIEF DESCRIPTION OF THE FIGURES

(1) Other advantages and characteristics will become clearer after reading the following description of a particular embodiment given as a non-limitative example of a system for activating the deployment of an inflatable safety vest for a skier according to the invention, with reference to the drawings in which:

(2) FIGS. 1 to 3 are partial perspective views showing different steps in the assembly of two main elements forming the activation system for deployment of an inflatable safety vest for a skier according to the invention.

BEST METHOD FOR IMPLEMENTING THE TECHNICAL INVENTION

(3) FIGS. 1 to 3 show an activation system 1 for deployment of an inflatable safety vest, net shown on the figures, Preferably for use by a skier, comprising a case 2 fixed to said inflatable vest and provided with a first opening 21 into which a box 3 containing the electronics can be reversibly placed, said first opening 21 comprising as the top part a housing 22 into which at least the top part 31 of the box 3 is inserted by an upwards movement to prevent trickling into the box (see direction D in FIG. 2).

(4) In this description, the activation system 1 for deployment of an inflatable safety vest worn by a skier upright on horizontal ground will be described. Obviously, the skier can be in another position and in this case terms such as for example horizontal, vertical, upper, lower, top or bottom should be used.

(5) Moreover, the term reversibly is used herein to denote the fact that the case 2 and the box 3 are designed to enable easy and fast placement (or on the contrary removal) of the box 3 in the case 2, these placement and removal operations possibly be done repeatedly with practically no limit to the number of these operations without damaging the case 2 or the box 3, and secondly can be done by anyone without any specific technical skills or special tools. In the case of a skier, these placement or removal operations can even be done when said skier is wearing gloves.

(6) The first opening 21 comprises support rails 23 on each side of the first opening 21, to support the box 3 at the bottom of said first opening 21 and sliding of the box so that it can be inserted in the housing 22, and a flexible attachment element 24 located in the bottom part of the first opening 21 and looking said box 3 in the inserted position. Said support rails 23 and the flexible attachment element 24 guarantee perfect locking of the box 3 in the inserted position in the housing 22, even under extreme conditions of use, so that the activation system 1 according to the invention can perform its detection function and its activation function for deployment of the inflatable safety vest.

(7) It is easy to understand that locking of the box 2 is also very easy and that operations to place and to remove the box 3 can be done very quickly, in less than 10 seconds, even when the skier is wearing gloves.

(8) At the bottom of the housing 22, the case 2 comprises connection means not shown on the figures, to make the connection between the case and the box 3, said connection means advantageously comprising sealing elements made from plastic and foam shapes.

(9) To facilitate installation, the connection means of the case 2 enable a wire type connection with the box 3.

(10) However, it will be understood that the connection between the case 2 and the box 3 could be of the wireless type making use of technologies such as for example the Bluetooth technology or the RFID (radio frequency identification) technology, without going outside the framework of the invention.

(11) According to one preferred embodiment, the case 2 is fixed to a dorsal protection 4 fixed on said inflatable safety vest, located behind the skier's lumbar vertebrae when said vest is worn by the skier and is made from an absorbent foam. Said case 2 also comprises a second opening 25 to hold inflation means capable of generating or releasing gas for deployment of the safety vest, not shown on the figures, these means advantageously being a compressed gas cartridge.

(12) According to one variant embodiment not shown, the inflation means are integrated into the box 3 and for example can be inserted in a recess made on said box 3.

(13) The box 3 comprises an electronic card, not shown on the figures, including at least functions for movement analysis, detection of a risk situation in relation to several types of sensors, activation of inflation means that in the preferred embodiment consist of a fast release of gas contained in the compressed gas cartridge.

(14) Said electronic board also comprises connection means and wireless communication means. The box 3 also comprises an energy storage device, not shown on the figures, advantageously of the rechargeable type capable of supplying energy to said electronic card to activate the inflation means.

(15) The box 3 that has the global shape of a parallelepiped is nevertheless made asymmetric in its top part 31, this asymmetry being at least partly repeated on a pattern 26 made on the case 2, so that it can only be positioned and inserted in a single direction.

(16) Furthermore, the longitudinal sides of the box 3 comprise attachment elements 32 designed to cooperate with and to be inserted in the support rails 23 of the case 2.

(17) The upper part 31 of the box 2 comprises additional equipment such as at least one switch, a micro-USB port for charging the battery and transferring data to a computer, and a power supply connector for the inflation means. The shape of this additional equipment and said connection means between the box 3 and the case 2 is complementary to the shape of the sealing elements of the case 2 so as to guarantee an excellent seal between the case 2 and the box 3 when the box is inserted in the housing 2 and blocked in position by the support rails 23 and the flexible attachment element 24.

(18) Furthermore, it will be understood that when the box 2 is inserted upwards and penetrates inside the housing 22 of the case 2, its upper part 31 is protected because it is covered by the wall of the housing 22 (see FIG. 2), the entire connection zone between said upper part 31 and the case 2 then being protected. Furthermore, even if the box 2 is removed, the connection means of the case 2 remain protected.

(19) Thus, since it is particularly easy to put into place or remove the box 3 in the case 2, the skier can carry several boxes and replace then when the energy storage device of the box connected inside the case 2 is discharged. He or she can also recharge or update a box 3 while continuing to use the activation system 1 according to the invention and the associated safety vest.

POSSIBILITY OF INDUSTRIAL APPLICATION

(20) It will be understood that the activation system 1 for deployment of an inflatable safety vest according to the invention is preferably for use by skiers. However, it is obvious that the activation system 1 according to the invention can be adapted to and used for inflatable safety vests, for example worn by a motorcyclist.

(21) Finally, it is obvious that the examples of the activation system 1 for deployment of an inflatable safety vest according to the invention as described above are simply particular illustrations and are not in any way limitative of the invention.
