Vehicle seat arrangement with an electric adjustment mechanism
First Claim
1. Vehicle seat arrangement, comprising:
- a) at least one electric adjustment mechanism;
b) at least one vehicle seat component;
c) at least one direct current motor provided for the adjustment of the at least one vehicle seat component, the direct current motor including direct current terminals configured for receiving a motor current;
d) a control device for controlling or regulating the at least one direct current motor, and the control device applies a direct current to the direct current terminals, in use, based upon the adjustment speed to be set;
e) the control device actuates the at least one direct current motor device upon receiving a comfort adjustment signal, in use, for providing a gradual comfort adjustment of the at least one vehicle seat component;
f) the control device activates the at least one direct current motor upon receiving a pre-crash signal, in use, for providing a rapid pre-crash adjustment of the at least one vehicle seat component from an initial position to a safe pre-crash position;
g) a memory device provided for storing adjustment data for the safe pre-crash position and the initial position, the memory device being configured for storing adjustment data prior to the pre-crash adjustment, in use; and
h) the control device activates the at least one direct current motor upon receiving a pre-crash signal, in use, and implements the rapid pre-crash adjustment at a load and an acceleration that are the maximum permissible load and acceleration for the at least one direct current motor at a respective operating point, in use.

Abstract
Vehicle seat arrangement includes an electric adjustment mechanism, a direct current motor for adjusting a vehicle seat component, with direct current terminals configured to receive a motor current. a control device for controlling or regulating direct current motor, which applies direct current to the direct current terminals based upon adjustment speed to be set. upon receiving a comfort adjustment signal control device actuates direct current motor for a gradual comfort adjustment of vehicle seat component, upon receiving a pre-crash signal control device actuates direct current motor for a rapid pre-crash adjustment of vehicle component from a current initial position to a safe pre-crash position. Adjustment data for safe pre-crash position and initial position are stored in a memory device prior to pre-crash adjustment, and rapid pre-crash adjustment is implemented at a load and acceleration that are the maximum permissible for direct current motor at the respective operating point.
