Abstract
A method and a device for adjusting a seat are provided. The method includes the acts of detecting a pressure exerted by a user on the seat via a pneumatic sensor and/or a hydraulic sensor, and adjusting the seat based on the pressure exerted by the user. The device includes a pneumatic or hydraulic lifting element, a pneumatic or hydraulic pressure sensor connected to the lifting element, and a control unit connected to the pressure sensor. The pressure sensor detects a pressure exerted by a user on the seat, and the control unit controls the first lifting element to adjust the seat based on the pressure exerted by the user.
Claims15
A method for adjusting a seat of a vehicle, wherein the seat comprises two sensors that detect pressure exerted by a user on a backrest of the seat, in spatially separate regions of the backrest, the method comprising the acts of:
- detecting a first pressure by a first one of the two sensors for the backrest,
- detecting a second pressure by a second one of the two sensors for the backrest,
- calculating a first pressure ratio of the first pressure to the second pressure,
- comparing the first pressure ratio with a first predetermined ergonomic pressure ratio, and
- adjusting, via an electric drive, a position of the seat with respect to the vehicle based on the comparing of the first pressure ratio with the first predetermined ergonomic ratio, wherein:
- the acts are repeated until the first pressure ratio is within a predetermined range of tolerance of the first predetermined ergonomic pressure ratio,
- the first pressure is an average of pressures exerted by the user on at least a first position and a second position within an upper region of the backrest, wherein the first position is spatially separated from the second position, and
- the second pressure is an average of pressures exerted by the user on at least a third position and a fourth position within a lower region of the backrest, wherein the third position is spatially separated from the fourth position.
A device for adjusting a seat of a vehicle, the device comprising:
- a first sensor that detects a first pressure exerted by a user on an upper region of the backrest,
- a second sensor that detects a second pressure exerted by the user on a lower region of the backrest,
- a control unit connected to each of the sensors, and
- an electric drive connected to the control unit, wherein:
- the control unit calculates a first pressure ratio of the first pressure to the second pressure,
- the control unit compares the first pressure ratio with a first predetermined ergonomic pressure ratio,
- the control unit controls the electric drive to adjust a position of the seat with respect to the vehicle until the first pressure ratio is within a predetermined range of tolerance of the first predetermined ergonomic pressure ratio,
- the first pressure is an average of pressures exerted by the user on at least a first position and a second position within the upper region of the backrest, wherein the first position is spatially separated from the second position, and
- the second pressure is an average of pressures exerted by the user on at least a third position and a fourth position within the lower region of the backrest, wherein the third position is spatially separated from the fourth position.
