Roping harness with improved seat

A roping harness is composed of a belt and a supporting seat joined to one another by joining straps, and comprising an attachment device. The seat is provided with means for adjusting the width to suit the user's morphology.

BACKGROUND OF THE INVENTION

The invention relates to a roping harness composed of a belt and a supporting seat joined to one another by joining straps and comprising an attachment device. Harnesses of this kind are generally used by professionals working at heights with secured progression on ropes, and in particular by tree trimmers.

STATE OF THE ART

Different harness sizes are proposed by manufacturers according to the weight and sex of the users, and also on the different categories of working at heights. There are generally three or four sizes to cover all the dimensions of each model of a range. This multitude of sizes results in production management and storage problems for the manufacturer, and also in procurement and storage problems for wholesalers.

OBJECT OF THE INVENTION

The object of the invention consists in providing a roping harness having a standard seat providing comfortable support for several different user sizes.

The device according to the invention is characterized in that the seat is provided with width adjustment means to adjust the width of the seat to suit the user's morphology.

According to a preferred embodiment, the seat comprises two telescopic parts mounted sliding in a rigid base, and symmetrical with respect to the vertical mid-plane of the base.

The two parts making up the seat preferably present identical structures each having a raised nose-shaped end-part and a flat surface provided with at least one series of holes for adjusting the width of the seat.

The invention also relates to a seat designed to be associated by straps with a roping harness. The seat is characterized in that it is provided with means for adjusting the width to suit the user's morphology.

DESCRIPTION OF A PREFERRED EMBODIMENTS OF THE INVENTION

With reference toFIGS. 1 to 4, a roping harness10is composed of a belt11and a supporting seat12joined to one another by joining straps13. Belt11is equipped at the front with a closing buckle14and with a ventral attachment device15.

Straps13are shaped as a pair of leg loops to form a sit harness strengthened at the base by the support seat12for the user to sit on.

Seat12comprises a hollow base16arranged as a slide, and two telescopic parts17a,17bhoused inside the slide in a manner enabling the width to be adjusted. The two parts17a,17bforming seat12present identical structures each having a raised nose-shaped end-part18a,18bsalient from the slide and a flat surface19a,19bprovided with two series of parallel holes20a,20b.

The rigid base16is provided with four holes21for securing screws22to pass through, the screws then passing through the respective holes20a,20bof telescopic parts17a,17bfor adjustment of the width of seat12.

For example, base16is made from metal whereas the two adjustable parts17a,17bare made from injected plastic material. A single mould is required for manufacturing telescopic parts17a,17b.

With reference toFIG. 3, the two opposite parts17a,17bof support seat12are symmetrical with respect to the vertical mid-plane of base16. It is thereby easy to adjust the width of seat12to the user's morphology while at the same time ensuring that said seat is centred with respect to the mid-plane.

According to a development of the invention, adjustable-width seat12can form a sub-assembly distinct from the harness and be sold separately. It can be joined to any type of harness by means of two attachment straps securedly affixed to nose-shaped end-parts18a,18b.
