Abstract: The invention relates to a composite material part including chips (1), each chip (1) having a substantially constant thickness defined between two parallel opposite faces (4) of the chip, each chip including carbon fibres (3) which are at least partly included in an adhesive cured during a first curing prior to the formation of said part, at least a majority of said fibres of the chip extending substantially parallel to said opposite faces (4) of the chip and a matrix (2) in which each chip (1) is at least partly included, said matrix (2) being formed of a cured adhesive during a second curing, such that a bonding interface is formed between the matrix (2) and each chip of the part.

Abstract: The present invention relates to a chip made from composite material containing carbon fibres in a cured adhesive, said chip having a substantially constant thickness defined between two parallel opposite faces of the chip, the surface of each face comprising carbon fibres that are at least partially not included in the cured adhesive.

Abstract: A seat intended to be fixed to the floor of a vehicle; includes a seat part incorporating a lower frame, and a backrest incorporating an upper frame secured to the lower frame by at least one fastener that allows the backrest to tilt in the event of an impact, by rotation about a transverse axis. The fastener includes a link rod having a first end connected to the lower frame by a first pivot link of axis parallel to the transverse axis, and having a second end connected to the upper frame by way of a second pivot link of axis parallel to the transverse axis. Each pivot link has a rotation brake, and/or a system of stops limiting its rotation amplitude; A sacrificial mechanical link connects the lower frame to the upper frame while being situated next to the link rod.

Abstract: The invention relates to a vehicle seat, preferably multiple-seater, which is deformable at the centre thereof and makes it possible to respond to deformation stresses in the event of an accident, impact or crash. In the case of a three-seater seat, the seat is primarily formed by four legs (10), a central seat portion (12), two end seat portions (11) and three backrests (13). The seat portions are bordered by two side bars (18) and one front bar and one rear bar. The front and rear bars are each formed by a central bar (14) or (16) which is extremely flexible, while the end bars (15, 17) of the end seats (11) are extremely rigid. The invention can also be used in aircraft seats.

Abstract: A device for locking a folding element in position for a vehicle seat including: a fixed element, designed to be fixed to the vehicle seat, a rotating element, designed to be fixed to the folding element, installed free to rotate relative to the fixed element about a rotation axis (X), the rotating element comprising at least a first locking structure, and a locking element, installed on the fixed element and that can be moved between a locking position in which it locks the rotating element in rotation relative to the fixed element by at least partial engagement of the locking element in the at least one first locking structure of the rotating element, and a release position in which it allows free rotation of the rotating element from the fixed element by release of the locking element in the at least one first locking structure of the rotating element.
