Described is a fixing device for fixing together a first and a second structure, each of said structures having at least a first and a second cavity, the device comprising a first and a second fixing element, each fixing element having a body comprising a seat and a pin, wherein: the pin of the first fixing element is configured to be inserted, freely passing through, in the first cavities of the first and of the second structure and to be reversibly coupled to the seat of the second fixing element, and the pin of the second fixing element is configured to be inserted, freely passing through, in the second cavities of the first and of the second structure and to be reversibly coupled to the seat of the first fixing element.

An insulating element for sealing off a structural element in a motor vehicle includes a carrier and an expandable material that is arranged on the carrier. The insulating element has a top side and a bottom side, wherein at least three contact points are arranged on each of the top side and the bottom side, which are designed in such a way that, when a plurality of identical insulating elements are stacked, adjacent insulating elements respectively lie on one another via these contact points and are thus arranged parallel to one another.

An undercover (31) for rectifying airflow under a floor of a vehicle while driving the vehicle includes screw pedestals (42) for fixing screws (41) or nut pedestals for nuts, which are served as fastening points to a vehicle body (29). Interference caps (58) which are a molded product made from an elastic resin material are fitted between the adjacent pedestals. Under a state that the undercover (31) is engaged with and is attached to the vehicle body by the screws, a top portion (60) of the interference caps (59) is elastically deformed and is abutted to the opposite vehicle body surface, and the above abutment is maintained. Small clearance between the undercover and the vehicle body are maintained, and interference between the undercover and the vehicle due to vibration while driving is prevented, without changing the number of fastening points of the undercover to the vehicle body.

The invention relates to a sound protection screen with an external shell made of a moulded thermoplastic material, an internal sub-layer based on resiliently compressible moulded polyurethane foam. The sub-layer is over-moulded with the rear side of the external shell. by over-moulding The shell is based on a sheet of thermoformed thermoplastic material and has a thickness between 0.2 and 1 mm. The shell can be a two-layered shell, with an external layer based on polyolefin. The external layer having at the side of the sub-layer, in order to allow adhesion between the shell and the sub-layer, with a rear layer based on a thermoplastic material that adheres to the foam. The shell can also be a single layer based on polyolefin, the rear side being subjected to a surface treatment that allows the adhesion to the sub-layer to be improved.

A vehicle partition configured to separate a first region and a second region of a vehicle cabin is provided. The vehicle partition may include a first panel member having a first attachment member configured to attach to a first seat of the vehicle cabin, a second panel member having a second attachment member configured to attach to a second seat of the vehicle cabin, and a third panel member connecting the first panel member to the second panel member. The first panel member may include a first panel and a first angled edge that is angled away from the first panel. The second panel member may include a second panel and a second angled edge that is angled away from the second panel.

A vehicle roof lining includes a roof lining, a rail structure, a multifunction plate, and sleds. The rail structure is provided on both side edges of the roof lining. The multifunction plate is provided on the roof lining, with one edge of the multifunction plate being movable along the rail structure. The sleds are movable along inner portions of the rail structure and are fastened with one edge of the multifunction plate.

A sheathing arrangement for an exhaust system of an internal combustion engine includes at least one sheathing element (18) with a sheathing element shell (19). On an inner side (30) of the sheathing element shell (19) insulation material (38) overlaps the inner side (30) in at least some areas. The inner side is to be positioned facing toward a component of an exhaust system (10), which component is to be sheathed. The insulation material (38) is fixed to the sheathing element shell (19) by means of at least one fastening element (40) passing through the sheathing element shell (19) and the insulation material (38).

Described is a fixing device for fixing together a first and a second structure, each of said structures having at least a first and a second cavity, the device comprising a first and a second fixing element, each fixing element having a body comprising a seat and a pin, wherein: the pin of the first fixing element is configured to be inserted, freely passing through, in the first cavities of the first and of the second structure and to be reversibly coupled to the seat of the second fixing element, and the pin of the second fixing element is configured to be inserted, freely passing through, in the second cavities of the first and of the second structure and to be reversibly coupled to the seat of the first fixing element.

A hollow chamber blocking tool includes: a first blocking tool having a first foamable base material on a first holder plate; and a second blocking tool having a second foamable base material on a second holder plate. The first blocking tool includes a steel plate fixing portion locked to a steel plate. The second blocking tool includes an integrated portion locked to the steel plate fixing portion. The second holder plate includes a rotating portion rotatably connected to the first blocking tool.
