A needled nonwoven for the manufacture of, in particular, textile wheel arch liners, has different materials in its individual layers across the thickness.

A low-noise pocket-type wheel guard is provided and includes a guard that is installed to face a surface of a tire in a vehicle, in which a noise reduction pocket is formed to protrude toward an interior of the vehicle in the guard. Since the noise reduction pocket is formed on the end portion of the wheel guard, in which a sound field is expected to be formed due to tire pattern noise, formation of a sound field due to the tire pattern noise is disturbed and prevented.

An exterior structural trim part for a vehicle, comprising at least an area comprising at least 3 layers superposed and laminated together to form a structural unit whereby the two outer layers are compressed and consolidated fibrous layers and with an inner layer situated in-between the two fibrous outer layers being an impervious polyester foam layer.

A fender liner that is to be placed in a curved shape along a periphery of a tire of a vehicle includes: a first foam layer that is formed by a first foam body; and a mixed layer that includes a first non-woven fabric and a second foam body that is foamed inside the first non-woven fabric, wherein the first foam body forming the first foam layer is seamless with the second foam body included in the mixed layer.

An apparatus and method for improving the safety and performance of an automobile in crash events is disclosed. The apparatus includes a front crash pad, rear crash pad, and a connection beam. Both crash pads and the connection beam are coupled to an automobile in such fashion as to absorb and dissipate energy by converting kinetic energy into strain energy.

A device for reducing a rolling noise of a vehicle having at least one tire, the tire rolling on a roadway on a tire contact patch, wherein the device comprises at least one sound absorption element attached to the vehicle in front of, behind and/or laterally of the tire contact patch in the direction of travel (F) of the vehicle and having at least one resonance frequency and a curved first absorber membrane facing the tire contact patch, wherein the entire first absorber membrane is oriented normally to a direction of sound propagation (S) emanating from the tire contact patch, and the sound absorption element is located at a distance from the tire contact patch which corresponds to a multiple of half a wavelength (λ) assigned to the resonance frequency.

A motor-vehicle underbody liner, encompassing a planar porous open-cell carrier component; the carrier component being embodied for mounting onto a motor-vehicle underbody and for being carried along therewith; the carrier component including an installation side that faces toward the motor-vehicle underbody during operation as intended, and a liner side that faces away from the motor-vehicle underbody during operation as intended; the carrier component being adjusted, by suitable densification of its open-cell material, to a sound absorption behavior having a sound absorption maximum in a frequency range from 800 Hz to 1250 Hz; there being arranged on the installation side of the carrier component an additional absorber component having a sound absorption behavior whose sound absorption maximum is also located in a frequency range from 800 Hz to 1250 Hz.

A fender liner that is to be placed in a curved shape along a periphery of a tire of a vehicle includes: a first foam layer that is formed by a first foam body; and a second foam layer that is formed by a second foam body, the second foam body having a composition different from a composition of the first foam body, wherein the first foam layer and the second foam layer are arranged in a circumferential direction of the tire.

A sound absorbing structure includes a vehicle structure having a surface and at least one acoustic scatterer coupled to the surface. The at least one acoustic scatterer has a resonant frequency. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end, the channel open end being in fluid communication with the opening. The sound absorbing structure may be configured to absorb sound waves at a certain frequency generated by a noise source. The certain frequency may be substantially similar to the resonant frequency of the at least one acoustic scatterer.

A vehicle lower structure is provided with an underbody cover installed to cover a vehicle body lower surface from below, a noise insulating material laid on an upper surface of the underbody cover, and a locking member fixed to the underbody cover while being laid on the noise insulating material.
