The exhaust muffler comprises a body (12) of ceramic material which is enclosed within a metal case (1) defining an inlet chamber (16) and an outlet chamber (18) for the exhaust gases. A blanket (20, 22) of refractory fibres resisting high temperatures, assembled with a very small amount of binder and substantially without water of constitution, is highly compressed between the body (12) and the case. A sealing element (24) surrounding the body (12) is interposed between the blanket and the gas outlet chamber (18).

Exhaust muffler for a motor vehicle or the like

This sub-assembly is formed by two shafts (1, 2), an inner and an outer shaft respectively, of which the surfaces facing one another are in contact locally in the vicinity of diametrically opposite points (16, 18), a space (22) being provided between them between the contact zones. These contact zones (8, 10, 12, 14) are pressed together as a result of force-fitting and elastic deformation, the inner shaft (1) initially having extra thicknesses, while the cavity of the outer shaft has portions narrower than these extra thicknesses. The shafts can, however, shift axially under the effect of a substantial shock.

Telescopic sub-assembly for a steering column

The tubular part (1) passes through a middle support piece (25) which is arranged between two clamping flanges (17a, 17b). A tie rod (21) passes through the flanges (17) and bears against the external surfaces of these flanges by means of a stop (29) and a clamping device on the one hand, and a nut (31), on the other hand. The clamping device consists of a bistable toggle-joint system comprising two levers (40,41) located in between the stop (29) and a bearing part (34). The stop (29), the levers (40,41) and the bearing part (34) have complementary hinging surfaces which are freely engaged with each other for assembly of the clamping device. With the device according to the invention it is possible to fix a steering column which can be continuously adjusted by pivoting and/or sliding. It is also possible to absorb the torques which may be transmitted to the steering column when the anti-theft device of the vehicle is engaged.

Fixing device for a tubular part, in particular for the steering column

This shaft is formed by a tube in a single piece having one end portion which is enlarged and cut away so as to constitute a universal joint yoke 5. A main cylindrical body 18 having a wall of reduced thickness connects this yoke to a portion 23 of greater wall thickness and provided with two slots 22 constituting a locking keeper. At the end of the shaft opposed to the yoke there is formed a steering wheel support constituted by a portion of the tube which has a smaller diameter and a greater wall thickness.
