Abstract
A housing for a vibration unit which can be arranged on a seat cushion of a vehicle seat and is intended to generate a haptically detectable signal at the vehicle seat. In order to enhance the driving experience of an occupant, in particular a driver, of a vehicle, the housing has an edge-free surface and at least one housing opening, which is permeable to sound waves.
Claims10
A method for producing a seat cushion for a vehicle seat, the method comprising:
- providing a vibration unit having at least one electrically controllable vibration device for generating vibrations, and a housing completely accommodating the at least one electrically controlled vibration device and configured to be arranged within the seat cushion of the vehicle seat such that the at least one electrically controllable vibration device generates a haptically detectable signal at the seat cushion, the housing having an edge-free surface and at least one housing opening, wherein the at least one housing opening is permeable to sound waves;
- foaming and curing a plastic within a molding tool;
- and
- arranging at least one plastic pocket for accommodating the vibration unit within the molding tool such that it is largely embedded in the seat cushion and a pocket opening is integrated into an outer surface of the seat cushion or is arranged outside the seat cushion.
