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.
Claims6
A vibration unit for generating a haptically detectable signal at a seat cushion of a vehicle seat, the vibration unit comprising:
- 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 the 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, and wherein the housing is configured as a triaxial ellipsoid.
A vibration unit for generating a haptically detectable signal at a seat cushion of a vehicle seat, the vibration unit comprising:
- 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 the 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, and wherein the housing is configured as kidney-shaped.
A seat cushion for a vehicle seat, the seat cushion comprising:
- 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, wherein the housing is configured as one of a triaxial ellipsoid and kidney-shaped.
