The invention relates to needleless syringe for injecting an active liquid principle. The inventive syringe comprises a container () closed by a movable shutter and containing the injectable liquid. Said container is initially insulated from an injector-receptacle provided with a cylinder bore () in which a downstream shutter is arranged and which comprises at least one protuberance reducing the section with respect to the upstream opening of the bore. The aim of said invention is to damp and prevent the downstream shutter bounce when it is disposed in the bore () of the receptacle.

Set of equipment () for a motor vehicle includes an inflatable structure (), a support () for the inflatable structure, elements for () inflating the structure in a direction of inflation (D) in order to deploy it, a plate () for spreading the load when an occupant of the vehicle impacts on the deployed inflatable structure, and elements for guiding the structure as it deploys so that, in the deployed configuration, the structure extends along a median directrix line (L) distinct from its direction of inflation (D). The guide elements include the side wall () of the structure which, in the deployed configuration, is substantially taut.

The technical field of the invention is that of pyrotechnic actuators comprising a piston, the basic function of which is to exert a thrust so as to displace an object by shooting out the piston. More particularly, the invention relates to a pyrotechnic actuator () comprising a pyrotechnic-gas generator (), a combustion chamber () and a piston () which can move in a slide chamber () under the effect of the said gases. The principal characteristic of this actuator is that it comprises a shut-off device (, 4) used after the triggering of the said actuator () in order, on the one hand, to close the slide chamber () and, on the other hand, to secure the depressurization of the combustion chamber ().

Pyrotechnic actuator of the variable-thrust-acting type

A damping device used for motor vehicle safety, for damping the displacement of at least one part set in motion during a collision between a motor vehicle and an external object, the part being, for example, a bumper, a steering column or a bonnet of a motor vehicle, the device comprising an actuator that is able to displace a piston and is characterized in that it includes a wire having one end connected to a fixed portion of the vehicle, the actuator, which is secured to the part to be damped, interacting with the wire in order to retard and then stop the part.

The technical field of the invention is that of motor vehicle safety involving energy absorption systems for damping the displacement of certain parts that are put into motion at the time of a mechanical collision between the motor vehicle and an externals object. The subject of the present invention relates to an energy absorption system for safety devices in a motor vehicle, comprising a pyrotechnic gas generator and a sliding position that can be displaced in a damping chamber, the said generator being able to release gas into the said chamber in order to damp the piston. The main characteristic of this system is that the gas generator delivers a variable quantity of gas and the damping chamber comprises a pressure-regulating device that is triggered above a threshold pressure.

A safety device for lifting a bonnet of a motor vehicle in the event of a collision, the device being situated under the bonnet. The device includes a mechanism for lifting the bonnet, and a gas generator. The bonnet includes a structure allowing the bonnet in normal operation, to be opened or closed about a rotation axis. The device also includes an actuator with a mechanical means actuated using the gas generator and able to deploy the lifting mechanism.

The invention concerns a protective assembly ( ) for the lower limbs ( ) of a motor vehicle passenger comprising an actuating device ( ) secured to the vehicle and capable of displacing a rod ( ) which is linked to a protective system. The invention is characterized in that: i) the actuating device contains a pyrotechnic system ( ); ii) the protective system comprises a protective cushion ( ) mounted on a shaft ( ) integral with the vehicle; iii) said protective cushion is mobile in rotation under the effect of the displacement of the rod so as to accompany, in the contact zone provided between the passenger's lower limbs and said protective cushion, the movement of said lower limbs.
