A sit safety harness comprises a pair of thigh loops in the form of closed loops and a belt with a central clasping device. Adjustment of the size of each thigh loop is performed by means of a clamping buckle fixed to the belt by an attachment strap and an adjustment strap securedly affixed by its end to the loop. The latter remains closed permanently throughout adjustment.

A self-jamming safety device for a rope comprises two pulleys, one of which is fixed on a base flange, and the other on a support plate capable of pivoting on an articulation spindle. The pulley is provided with a first braking surface, against which the rope is pressed by a boss of the pulley when the support plate is driven by the tension of the rope to a first jamming position. The pulley is equipped with a second braking surface operating in conjunction with the first surface following continued pivoting movement of the support plate to a second jamming position. Switching between the two jamming positions takes place after the tension of the rope has exceeded a preset threshold.

A casing for cylindrical electrical batteries of different diameters is equipped with adjustment means with pivoting spacers designed to occupy a first inactive position or a second active position in order to keep the positioning of the longitudinal axis of each battery, regardless of its diameter.

Self-jamming descender for a rope with two jamming positions

A portable lamp, especially for mounting on the head of the user, includes an adjustment collar designed to ensure displacement of the reflector causing a variation of the light beam focus, and operation of the bulb switch. The lamp comprises a single casing having an insulating body subdivided by an intermediate wall into a first rear compartment housing the power supply unit, and a second front compartment housing the bulb and the adjustable focusing device. The wall is provided with a communication orifice between the two adjacent compartments, and with a fixed sleeve to house the bulb. The switch is composed of an elastic contact blade cooperating with a flange of the reflector. Refer to FIG. 1.

Compact waterproof lighting lamp with adjustable light beam

An electric lamp with a parabolic reflector in a threaded collar, provided with a device for adjusting the focus by relative displacement between the bulb and the reflector which occurs when turning the collar on its threads between first and second adjusting positions. The device furthermore controls a switch housed within the casing for the device. The device is particularly applicable as an electric headlamp for mountain-climbers or spelunkers.
