<p>The safety belt (1) comprises a tubular sheath (10) made of non-stretchable material, and a set of elastic thread related to the sheath. The safety belt is movable by elasticity between a rest position and an extended position. The elastic thread defines longitudinal areas of weaving in which threads are woven on single face (11, 12) of the sheath so that the belt has a snail shape in rest position. Each longitudinal areas of weaving is adapted to form, in the resting position, bending areas (Z1, Z2.....Zn) in which the elastic threads are folded on each other. The safety belt (1) comprises a tubular sheath (10) made of non-stretchable material, and a set of elastic thread related to the sheath. The safety belt is movable by elasticity between a rest position and an extended position. The elastic thread defines longitudinal areas of weaving in which threads are woven on single face (11, 12) of the sheath so that the belt has a snail shape in rest position. Each longitudinal areas of weaving is adapted to form, in the resting position, bending areas (Z1, Z2.....Zn) in which the elastic threads are folded on each other. Each bending areas form a circular sector, where a center (C1, C2....Cn) of the circular sector is located on the side of the face of the sheath. An axial dimension of longitudinal areas of weaving with elastic threads is 4 cm. The longitudinal areas of weaving with elastic threads extend alternately on one and other of the faces of the sheath, and extend over entire axial dimension of the belt. Each bending area extends along an angle of 180-270[deg] so that two connecting lines (L1, L2...Ln) between consecutive weaving areas are adjacent. The connecting lines between consecutive weaving areas are aligned, in the rest position, along a longitudinal axis of the belt. The elastic threads form 5-20% chain threads (CH11 + CH2, CH12 + CH2) for a given weaving area. An independent claim is included for a process for fabricating a safety belt.</p> |
