Disclosed is a fully enclosing engine or unit capsule of a motor vehicle with an air cushion foil, whereby the acoustic component properties can be significantly influenced, tuned.

Fully enclosing engine or unit capsule of a motor vehicle with air cushion foil

A sound insulation element for the wall of a vehicle body between the passenger compartment and the engine compartment has a front side facing the passenger compartment formed by the outer side of A plastic carrier layer, and a rear side which rests against the front wall formed by the outer side of a sound-absorbing layer. At least one holding-down projection projects from the plastic carrier layer at and/or offset from the edge of the hole of the carrier layer on the inner side of the plastic carrier layer facing away from the outer side of the plastic carrier layer facing the sound-absorbing layer, which is embedded in the sound-absorbing material of the sound-absorbing layer and whose free ends facing away from the plastic carrier layer are substantially aligned with the outer side of the sound-absorbing layer facing away from the plastic carrier layer.

Sound insulation element for the firewall of a vehicle body and support element for a sound insulation element of this type

The apparatus for fastening a vehicle component in and/or on a vehicle has a sound insulation element with a carrier layer and a sound absorbing layer. An anchoring recess is formed in the carrier layer and has an insertion opening in a first side of the carrier layer, which insertion opening is adjoined by a receiving space which is delimited by the plastic material of the carrier layer and is defined by a closed circumferential inner side and a closed bottom surface. An anchoring element is further provided. The anchoring recess has a constriction area formed on the circumferential inner side and at least partially narrowing the receiving space, with a widened widening area adjoining in the direction of the bottom surface. The anchoring element has an anchoring shoulder for engaging behind the constriction area when the anchoring element is received by the anchoring recess.

Apparatus for fastening a vehicle component in and/or on a vehicle

Apparatus for sound insulation of a machine has a sleeve which has a sound-absorbing composite material wall with a plastic carrier layer. The composite material wall has two edge regions which lie against and/or above one another and each have a boundary edge which can be connected by at least one plug-in connection arrangement. The at least one plug-in connection arrangement has a plug-in tab arranged in one first edge region of the composite material wall and a receiving element which is arranged in the other second edge region of the composite material wall and into which the plug-in tab can be plugged. The plug-in tab has a web which has an end connected to the plastic carrier layer and an end section facing away from this end and having an insertion end and an upper side and an underside with at least one locking recess.

Device for noise insulation of a machine

A noise insulation element () for the bulkhead () of a vehicle body () is provided with a mass-spring element () which has a plastic support layer () as the heavy layer with a front side facing away from the bulkhead () when the mass-spring element () is installed and with a rear side facing towards the bulkhead (), and a noise damping layer () made from a noise insulating material connected to the rear wall as the spring layer. The support layer () is provided on its rear side with an integrally designed hollow fixing projection () which is formed on an edge recess with a recess edge which recess is open towards an outer limiting edge section () of the support layer () and a side wall () projecting from the rear side of the support layer () and extending along the recess edge.

The present invention relates to filled thermoplastic polyolefin compositions useful e.g., as sound-deadening sheeting for formed automotive applications comprising a propylene polymer having a density equal to or greater than 0.885 g/cm, one or more linear ethylene polymer and/or substantially linear polymer, a plasticizer, and a filler, preferably calcium carbonate. Said composition demonstrates a good balance of heat properties and stiffness such that it is particularly suitable for sheet extrusion and thermoforming articles therefrom.
