Abstract
An activation system for actuators of a vehicle seat device, including a first control device; a gas pressure accumulator having a gas pressure accumulator valve situated on it; a pressure distribution device functionally connected to the gas pressure accumulator; and a connecting device situated between the first control device and the pressure distribution device, the actuators being activatable as a function of an accident characteristic which is ascertainable with the aid of the first control device and which is transmittable to the pressure distribution device.
Claims14
An activation system for actuators of a vehicle seat device, comprising:
- a first control device configured to control the actuators;
- a gas pressure accumulator having a gas pressure accumulator valve situated on the gas pressure accumulator;
- a pressure distribution device functionally connected to the gas pressure accumulator;
- and
- a connecting device situated between the first control device and the pressure distribution device, the actuators being activatable as a function of an accident characteristic which is ascertained by the first control device and which is transmitted to the pressure distribution device;
- wherein the pressure distribution device includes at least two gas outlet valves and a second control device configured to control the at least two gas outlet valves according to the accident characteristic.
A method for activating actuators of a vehicle seat device, comprising:
- ascertaining an accident characteristic by a first control device configured to control the actuators;
- transmitting the accident characteristic from the first control device to a pressure distribution device having at least two gas outlet valves and a second control device, wherein the actuators are activatable as a function of the accident characteristic ascertained by the first control device and transmitted to the pressure distribution device;
- controlling the at least two gas outlet valves of the pressure distribution device by the second control device as a function of the accident characteristic;
- and
- controlling, by the second control device, opening of a gas pressure accumulator valve of a gas pressure accumulator connected functionally to the pressure distribution device.
