The present disclosure relates to a vibration device configured to be integrated into a vehicle seat and comprising a vibrator capable of generating vibrations. This device further comprises an attachment mechanism capable of attaching the vibrator to the back or underside of a support layer integrated into a member of the seat, and a damper which is in contact with this support layer and with the vibrator, and which is capable of reducing, in the support layer, the vibrations generated by the vibrator.

A seat for vehicles has an assembly structure configured such that a cushion assembly may be mounted on and separated from a seat base through a locking device, and thus allows a cover member configured to cover the cushion assembly to be easily replaced so as to prevent contamination of the cushion assembly and the seat base and damage thereto, such as rust generation, due to contaminants on the cover member.

A vibration generation device (200) includes a frequency information recorder (80) configured to record frequency values of inputted measurement signals such that the frequency values are associated with measurement positions of vibrations on the seat originally generated by the vibration generator (20) on the basis of the measurement signals and transmitted to the seat by the vibration transmission member and an output signal generator (70) configured to obtain a frequency value of a measurement position corresponding to a desired position from the frequency information recorder (80) and to generate an output signal having the frequency value.

A vehicle seat includes a foam body having a first region, a second region, a top surface, and a bottom surface, and a trench defined by and between the first and second regions. The trench includes at least one section including a narrow portion having a first width and extending downwardly into the trench from the top surface, and a base portion below the narrow portion having a second width greater than the first width. The vehicle seat further includes a trim attachment fixture disposed in the foam body below the trench, wherein the trim attachment fixture is configured to be secured to a trim cover by an attachment member disposed in the base portion.

A cushion member 301 is a cushion member made of flexible resin or rubber and used for a passenger seat 300, and includes a porous structural body 1, and a top skin 330 serving as at least a surface FS on a seated person side among surfaces of the passenger seat and integrated with the porous structural body.

A foam part of a motor vehicle seat having seat occupancy detection, wherein the foam part includes a seat surface and an underside opposite to the seat surface, and wherein a number of seat occupancy detection sensors are arranged in the region of the underside and these sensors are fastened via a number of holding profiles on the foam part to detect a weight force acting on the seat surface. Furthermore, the invention comprises a method for producing such a foam part and a motor vehicle seat having foam part.

A seat cushion includes a cushion body defining a first body surface and a second body surface opposite the first body surface, wherein the first body surface is configured to face the seat occupant, and the second body surface is configured to face away from the seat occupant. The cushion body defines a plurality of holes extending into the second body surface or columns extending from the second body surface. The holes or columns are arranged on a pattern to allow the cushion body to passively conform to the seat occupant, thereby enhancing comfort.

A vibration generation device (200) includes a frequency information recorder (80) configured to record frequency values of inputted measurement signals such that the frequency values are associated with measurement positions of vibrations on the seat originally generated by the vibration generator (20) on the basis of the measurement signals and transmitted to the seat by the vibration transmission member and an output signal generator (70) configured to obtain a frequency value of a measurement position corresponding to a desired position from the frequency information recorder (80) and to generate an output signal having the frequency value.

The present invention relates to a vehicle seat system for reduction of vertical peak acceleration of a person seated in a vehicle seat during impact. The vehicle seat system comprises a seating structure and a trim at least partially enclosing the seating structure. The trim is releasably fastened to the seating structure by means of interconnected trim fastening means comprising at least two parts adapted to release from each other when the vertical peak acceleration exceeds a predetermined limit value, subsequently reducing the vertical peak acceleration. The present invention further relates to a vehicle comprising the vehicle seat system.

A seat cushion includes a cushion body defining a first body surface and a second body surface opposite the first body surface, wherein the first body surface is configured to face the seat occupant, and the second body surface is configured to face away from the seat occupant. The cushion body defines a plurality of holes extending into the second body surface or columns extending from the second body surface. The holes or columns are arranged on a pattern to allow the cushion body to passively conform to the seat occupant, thereby enhancing comfort.
