Lumbar support belt

A lumbar support belt having a vertical median axis of symmetry and a longitudinal axis, the belt comprising:

• two branches arranged to be positioned on either side of the lower portion of the trunk of a wearer, the branches each having a medial end portion and a lateral end portion, the medial end portions being linked to each other in the median area of the belt and the lateral end portions being provided with complementary attaching means to enable them to be assembled when they are placed on each other in the abdominal area of the wearer, the belt, when it is flat and in the unstressed state, being such that each branch includes:
• a first elastic strip extending from the lateral end portion to the medial end portion of the branch, according to a general direction upwardly inclined at an angle α with respect to the longitudinal axis of the belt;
• a second elastic strip extending from the lateral end portion to the medial end portion of the branch, according to a general direction downwardly inclined at an angle β with respect to the longitudinal axis of the belt;
• the first and second strips being superimposed, over a portion of their surface, in the anterior-posterior direction;
• wherein the first and second strips of each branch are configured and arranged with the lower lateral corner of the second strip which is offset vertically upwards with respect to the lower lateral corner of the first strip, so that, when the belt is flat and in the unstressed state, the branch has a non-rectilinear lower edge successively formed, from the lateral end portion to the medial end portion by:
• an upwardly inclined portion formed by a portion of the lower edge of the first strip;
• then a downwardly inclined portion formed by a portion of the lower edge of the second strip;
• the lower edge of the strip thus having a lower indentation configured to be located above a thigh of the wearer.
