Abstract: A device for collecting swell energy that comprises a float, a turbine mounted under the float and adapted for moving relative to the float when the float is moved by the swell, and a power generator driven by the turbine. The turbine is rotatingly mounted about a vertical rotation axis, so that a tilting motion of the float always results in a torque applied onto the turbine in a single predetermined rotation direction.

Abstract: The invention relates to a device for collecting swell energy, that comprises a float, a turbine mounted under the float and adapted for moving relative to the float when the float is moved by the swell, and a power generator driven by the turbine. The turbine is rotatingly mounted about a vertical rotation axis, said turbine being adapted so that a tilting motion of the float always results in a torque applied onto the turbine in a single predetermined rotation direction.

Abstract: Headrest (150) comprising a fixed part (111), a mobile part (112) opposite the fixed part, first (114) and second (115) connecting rods, each connecting rod comprising two branches, connecting the fixed part to the mobile part and two resilient devices acting on the first and second connecting rods to distance the mobile part from the fixed part. The first and second connecting rods respectively slide on the mobile and fixed parts and a third connecting rod (113) is provided to connect the fixed and mobile parts.

Abstract: The automobile vehicle seat features a seat back hinged on the seat pan and device for blocking the seat back with respect to the seat pan in the event of forward impact. The automobile vehicle seat features a height adjustment mechanism. The device for blocking the seat back includes a cam pivot-mounted on the shaft, and a weight joined to the cam, with the cam arranged so upon impact the cam, pivots by the inertia of the weight and the cam engages with a lower edge of the seat back frame, such that pivoting of the seat back is prevented by bracing of the cam against the lower edge and such that this produces a high radial force on the height adjustment shaft, thereby limiting the possibilities of rotation of the height adjustment shaft.

Abstract: The automobile vehicle seat features a seat back hinged on the seat pan and means for blocking the seat back with respect to the seat pan in the event of forward impact. It features a height adjustment mechanism. The seat back blocking means comprise a cam pivot-mounted on the shaft, and a weight joined to the cam, with the cam arranged so upon impact, it is caused to pivot by the inertia of the weight, it engages with a lower edge of the seat back frame, such that pivoting of the seat back is prevented by bracing of the cam against the said lower edge and such that this produces a high radial force (F) on the height adjustment shaft, thereby limiting the possibilities of rotation of the said height adjustment shaft.

Abstract: A braking system for braking a first element (2) pivotally mounted on a pivot pin (6) that is secured to a stationary second element (3). The system includes a helical spring (18) which has a diameter adapted so that, in the assembled state, said helical spring (18) is in contact against the inside wall (15) of a sleeve (14) secured to the second element, the helical spring (18) being adapted so as to make it possible, while the first element is pivoting, to increase the diameter of the helical spring (18) so as to increase the friction force between the helical spring (18) and the sleeve (14), thereby causing the pivoting of the first element (2) to be braked.

Abstract: Seat pan (3) of an automobile vehicle seat including an anti-submarining crossmember (6) which extends crosswise and which can move towards the rear from a rest position to an extension position and towards the front from the extension position. The crossmember (6) is installed so as to pivot around a transverse axis (A) on a sliding carriage (7) guided in translation on the seat pan framework. Extension means (10) are arranged to connect the crossmember (6) and the carriage (7) so as to pivot the crossmember in relation to the carriage from the rest position to the extension position and energy dissipation means (9) connecting the carriage (7) to the seat pan framework (5) to exert a retention force on the carriage during movement of the carriage forwards.

Abstract: A nautical propulsion device for amphibious vehicle wherein the rims 2 of the driving wheel tires 1 are provided with vanes 3 rotating with the wheels. Each of these wheels comprises, in the region where the liquid leaves the vanes 3, an open delivery channel 4 adjacent to and facing this region, and a delivery pipe 5 with its outlet facing backwards with respect to the desired travelling direction. If the driving wheels are also guiding wheels, the vehicle may be steered through the water simply by turning the wheels without any other drive being required. The wheels act as pumps using the reactional fare to propel the vehicle during nautical use.
