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.
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.
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.
Other advantages and features will become more clearly apparent from the following description of particular embodiments of the invention given for non-restrictive example purposes only and represented in the appended drawings in which:
With reference to
Straps 13 are shaped as a pair of leg loops to form a sit harness strengthened at the base by the support seat 12 for the user to sit on.
Seat 12 comprises a hollow base 16 arranged as a slide, and two telescopic parts 17a, 17b housed inside the slide in a manner enabling the width to be adjusted. The two parts 17a, 17b forming seat 12 present identical structures each having a raised nose-shaped end-part 18a, 18b salient from the slide and a flat surface 19a, 19b provided with two series of parallel holes 20a, 20b.
The rigid base 16 is provided with four holes 21 for securing screws 22 to pass through, the screws then passing through the respective holes 20a, 20b of telescopic parts 17a, 17b for adjustment of the width of seat 12.
For example, base 16 is made from metal whereas the two adjustable parts 17a, 17b are made from injected plastic material. A single mould is required for manufacturing telescopic parts 17a, 17b.
With reference to
According to a development of the invention, adjustable-width seat 12 can 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-parts 18a, 18b.
