Abstract: A mechanical device for maintaining a door in an open position, having an arm slidable in a guide body provided with shoes capable of spreading apart upon the passage of the arm, and springs having a resilient opposing action tending to move the shoes towards each other. According to the invention, the guide body has at least one surface element having a cylindrical outer shape, mechanically connected to the shoes and radially deformable. An opposing action is formed by at least one coil spring which is mounted coaxially around and in contact with the surface element. A preferred application of the device is for doors of motor vehicles.

Abstract: The cap comprises attaching devices and key-actuated locking devices which are independent from the attaching devices. This enables the cap to be shifted by hand without use of the key if desired. The locking devices comprise a plurality of elastically yieldable strips which are part of a single member which is fixed to the body of the cap. The end portion of each strip is located in alignment with an aperture of the body and bears against the bottom of a cam groove of a member which is connected to rotate with a lock barrel receiving the key.

Abstract: The protecting device comprises a vertebral column protecting element (2) presenting at its higher end a nape protecting element (3) and at its lower end a belt (1), a tight chamber extending on these three elements and being provided with automatically releasable inflating means (10).The protecting device can be beared as a harness by means of straps (15, 16) or incorporated to a clothing. It allows in case of accident to decrease the risks or the severity of injuries to the vertebral column, to the nape and to the lumbar region.
