The invention also relates to a vehicle provided with at least one holding device of the type mentioned above.

Abstract: A device for temporarily holding an opening element in an ajar position relative to a stationary element of a body of a vehicle, including a body provided with at least one mounting method, and a retaining method including a tab a first end of which is designed to cooperate with a first flange of a housing and a second end of which provides a junction with the body, wherein the tab includes, between the first end and the second end, an intermediate area including at least one section configured to distribute stresses applied to the tab when the device is moved to the ajar position or the fully open position.

Abstract: A method for manufacturing an alveolar core structure includes at least one cell including a secondary duct having a first end defining a sound wave inlet, and an opposite second end, the secondary duct comprising a sound wave outlet. The method also includes a fastening step in which adhesive tapes transverse to the longitudinal direction of said first plate are applied on a first longitudinal plate. The secondary duct in the form of a flattened element is fastened, on the first plate, by gluing at its sound wave inlet. A second plate is applied. A step of deploying the first and second plates so as to form the peripheral wall of the cells and so that the flattened element is deployed.

Abstract: An assembly includes a first part and a second part separate from the first part, the first and second parts being intended to be in frictional contact, the first part being made of an organic matrix composite material that has, on its surface, an abrasion-resistant area including a resin that contains polytetrafluoroethylene particles, the polytetrafluoroethylene particles being only present at the surface of the first part, and the second part being made of an organic matrix composite material and being in contact with the abrasion-resistant area of the first part.

Abstract: A method for manufacturing a preform for producing a part made of composite material with an unchangeable final shape includes supplying a triaxial non-woven textile comprising a layer of fibers orientated in a first direction, a layer of fibers orientated in a second direction, a layer of fibers orientated in a third direction, and seams extending parallel to each other and forming sheaths for the circumferential fibers, arranging the textile on an element of unchangeable shape by placing the seams parallel to the circumferential direction of the element, and sliding the circumferential fibers into the sheaths so that the textile is in continuous contact with the element.

Abstract: The present invention relates to a device (100) for holding an opening element in an ajar position on a stationary part of a body of a motor vehicle, comprising a spacing element (1) provided to be attached to a stationary part of the vehicle body or to the opening element, the spacing element (1) comprising a base (10) provided for attaching the spacing element (1) to the stationary part or to the opening element, characterized in that the spacing element (1) comprises: —a connecting member (30) attached to the base (10) and comprising an elastically deformable zone (32) designed to deform under the action of stresses exerted by a holding member presented by the opening element (200) or the stationary part, —a retaining member (40) attached to the connecting member (30) and comprising an elastically deformable zone (41) designed to deform under the action of stresses exerted by the holding member.

Abstract: An interface is intended to be fixed to a first rim edge of an opening element or of a fixed element of a motor vehicle body in order to protect a retaining portion of a device for temporarily closing the opening element on the fixed element provided in order to carry out the steps of painting the motor vehicle from contact with the rim edge. The interface has a portion in the general shape of a cage intended to house the temporary closing device. A kit including the interface and the temporary closing device is also described.

Abstract: The invention relates to an improved cleansable filter intended for filtering natural water for the irrigation of cultivated fields. The filter comprises a cylindrical body, a filtering element mounted inside said body and defining in the interior two concentric chambers, one communicating with the exterior through a drainage valve, and also through one of two lateral openings in the body. The other annular chamber encloses the first chamber and communicates with the exterior through the other lateral opening. The filter also comprises a brush mounted coaxially in said first chamber, said brush being rotatable manually or automatically from the exterior of the filter, and removing all foreign bodies from the inner wall of said first chamber. The liquid to be filtered enters the annular chamber through a lateral opening, passes into the first cylindrical chamber and through the filtering elements from the interior to the exterior, and leaves by the second lateral opening.
