Abstract
An energy absorber has a textile element comprising two substrates connected to one another by breaking links and resistant links, the textile element being wound. A container receives the textile element. The container defines a first opening for a first end and a second opening for a second end of the textile element. The resistant link connects a portion of the two substrates and maintains the connection in response to a first stress applied between the first end and the second end. The breaking links break and absorb energy in response to a first stress between the first end and the second end of the textile element. The container is non-openable and defines an access hole opening out facing the centre of the textile element in wound state.

An energy absorber comprising:
- a textile element comprising at least two substrates connected to one another by breaking links and at least one resistant link, the textile element being wound;
- a container receiving the textile element in wound state, the container defining a first opening for a first end of the textile element and a second opening for a second end of the textile element;
- wherein the at least one resistant link connects a portion of the at least two substrates and is configured to maintain the connection in response to a first stress applied between the first end and the second end;
- and
- wherein the breaking links are designed to break and to absorb energy in response to a first stress applied between the first end and the second end of the textile element;
- wherein the container is non-openable and wherein the container defines at least one access hole facing a center of the textile element arranged in wound state in the container.
A method for manufacturing an energy absorber comprising the following steps:
- providing a textile element comprising at least two substrates connected to one another by breaking links and resistant links, and a container defining a first opening, a second opening and at least one access hole opening inside the container;
- inserting a central part of the textile element in the container via the first opening until the central part of the textile element is facing the at least one access hole;
- connecting a winding shaft to the central part of the textile element, the winding shaft passing through the at least one access hole;
- winding the textile element inside the container by the winding shaft;
- inserting the second end in the second opening, the first end being in the first opening.
