Abstract
Description
Dispositif d'amortissement de choc destiné à limiter les accidents duShock absorbing device for limiting the accidents of the
rachi et autres lésions causées lors de l'atterrissage du pilote. rachi and other injuries caused during the landing of the pilot.
La présente invention concerne un dispositif d'amortissement de choc destiné à limiter les accidents du rachi et autre lésions pendant l'atterrissage du pilote. The present invention relates to a shock absorbing device for limiting accidents of rachi and other injuries during the landing of the pilot.
Le principal problème de sécurité pendant un vol libre en parachute ou en parapente est le nombre de traumatismes vertébraux dont sont victime les pilotes pendant l'atterrissage. The main safety issue during a free parachute or paraglider flight is the number of vertebral trauma experienced by the pilots during the landing.
La principale fonction de ce dispositif est de protéger le pilote lors d'un mauvais atterrissage. The main function of this device is to protect the driver during a bad landing.
Actuellement, il existe beaucoup de système de protection mais ceux-ci s'avèrent peu fiables à cause de l'utilisation de matériaux ayant un mauvais coefficient d'amortissement. De plus ils sont extrêmement volumineux donc lourd à transporter. Currently, there is a lot of protection system but these are unreliable because of the use of materials having a bad damping coefficient. In addition they are extremely bulky so heavy to carry.
La présente invention vise à pallier ces défaillances techniques et à pour objectif de fournir un dispositif fiable, qui assure une protection optimum pour le pilote lors de son atterrissage. The present invention aims to overcome these technical shortcomings and aims to provide a reliable device, which provides optimum protection for the pilot during his landing.
A cet effet, l'invention vise un dispositif de protection comprenant (figure 1) : Une assise (3) en mousse, par exemple PU ou PVC, dans laquelle deux systèmes en nid d'abeille écrasable (4) sont logés sous chaque fesse du pilote. Pendant la réalisation du prototype plusieurs systèmes pourront éventuellement être rajoutés (figure 3). For this purpose, the invention provides a protection device comprising (Figure 1): A seat (3) foam, for example PU or PVC, in which two crushable honeycomb systems (4) are housed under each buttock of the pilot. During the realization of the prototype, several systems may be added (Figure 3).
Ces systèmes d'amortissement sont de forme rectangulaire ou cylindrique. La conception de ceux-ci est en forme de sandwich (figure 4). These damping systems are rectangular or cylindrical. The design of these is sandwich-shaped (Figure 4).
C'est à dire que le système d'amortissement est une imbrication de trois plots en nid d'abeille. That is, the damping system is an interlocking of three honeycomb pads.
Deux plots en maille d'intervalle (13mm à 19mm) et d'épaisseur compris entre (30mm et 70mm) forment les parties inférieures et supérieures du sandwich et un plot en maille d'intervalle (13mm à l9mm) et d'épaisseur compris entre (5mm et 20 mm) réalise la partie centrale. Two knots interval mesh (13mm to 19mm) and with a thickness of between (30mm and 70mm) form the lower and upper parts of the sandwich and a spacer mesh pad (13mm to l9mm) and thickness between (5mm and 20mm) realizes the central part.
Ce sandwich permet d'obtenir de grandes caractéristiques d'amortissement car on travaille en compression pure. This sandwich makes it possible to obtain great damping characteristics because one works in pure compression.
Un dossier (2) en mousse, par exemple PU ou PVC, dans lequel un système en nid d'abeille écrasable (4) est logé au bas du dos du pilote. Pendant la réalisation du prototype plusieurs systèmes pourront éventuellement être rajoutés (figure 2). A folder (2) foam, for example PU or PVC, wherein a crushable honeycomb system (4) is housed at the bottom of the back of the driver. During the realization of the prototype, several systems may be added (Figure 2).
Ce système d'amortissement est également de forme rectangulaire ou arrondie cependant les mailles des plots sont différentes de celles de l'assise. Elles sont comprises entre 13mm et 25mm. This damping system is also rectangular or rounded, however the mesh of the pads are different from those of the seat. They are between 13mm and 25mm.
2873350 L'angle entre l'assise et le dossier est égal à 20 . 2873350 The angle between the seat and the backrest is 20.
Un répartiteur de choc (1) en mousse adhésive à forte densité qui sera en contact avec le pilote. Celui-ci recouvre et assemble les deux blocs de mousse c'est-à-dire assise (3) et dossier (2) (figure 1). A shock distributor (1) of high density adhesive foam that will be in contact with the pilot. This covers and assembles the two blocks of foam that is to say seated (3) and back (2) (Figure 1).
Une housse en matière aramide est utilisée pour que le dispositif soit protégé de toute agression extérieure (usure par frottement, salissure, perforation etc...) A cover in aramid material is used so that the device is protected from any external aggression (wear by friction, dirt, perforation etc ...)
