Abstract
A lane departure warning system for a vehicle includes a positional input device and a seat having an inflatable bladder therein and a vibrational unit coupled with the bladder. A controller is communicatively coupled with the positional input device and with the vibrational unit and includes electronic circuitry programmed to detect a lane departure based on a signal from the positional input device and to cause the vibrational unit to vibrate in response thereto.
Claims15
A lane departure warning system for a vehicle, comprising:
- a positional input device;
- a seat including:
- a cushion;
- a seat back coupled with the cushion;
- a carrier assembly within one of the cushion and the seatback, the carrier assembly including a body;
- an inflatable bladder;
- a vibrational unit;
- and
- a polymeric fastener that secures the inflatable bladder to the body of the carrier, wherein the vibrational unit is coupled with the bladder by being coupled with the polymeric fastener;
- and
- a controller communicatively coupled with the positional input device and with the vibrational unit and including electronic circuitry programmed to detect a lane departure based on a signal from the positional input device and to cause the vibrational unit to vibrate in response thereto a frequency of between about 80 Hz and 115 Hz to replicate a vibration of a seat in a vehicle traveling over a highway rumble strip.
A vehicle seating assembly, comprising:
- a seat base;
- a seatback coupled with the base;
- a headrest coupled with the seatback;
- a carrier disposed in an interior of at least one of the seat base, the seatback, and the headrest, and having an inflatable bladder coupled with the carrier by a polymeric connector and configured to move between a first position, wherein the bladder is deflated, and a second position, wherein the bladder is inflated;
- and
- a vibrational unit coupled with the polymeric connector and configured to generate a vibration of a frequency between 80 Hz and 115 Hz to replicate a vibration of a seat in a vehicle traveling over a highway rumble strip.
A motor vehicle, comprising:
- a positional input device;
- a seat having therein a carrier, an inflatable bladder coupled with the carrier by a polymeric fastener, and a vibrational unit coupled with the polymeric fastener;
- and a lane departure warning controller communicatively coupled with the positional input device and with the vibrational unit and including electronic circuitry programmed to detect a lane departure based on a signal from the positional input device and to cause the vibrational unit to vibrate in response thereto at frequency of between about 80 Hz and 115 Hz to replicate a vibration of a seat in a vehicle traveling over a highway rumble strip.
