Abstract
A closing device for opening and closing an opening in a vehicle is disclosed. The closing device comprises a closing system, having a closing body (SK) that is fitted on the vehicle (FZ) in a movable manner and is configured to open and close the opening (O), a drive device (AV) that is operatively connected to the closing body (SK) and is configured to move the closing body (SK), and a transmission system (US) that is arranged between the closing body (SK) and the drive device (AV) and is configured to transmit a drive force generated by the drive device (AV) to the closing body (SK). The closing system (SLS) has a closing system spring rate (FRSLS) that characterizes an overall elasticity of the closing body (SLS), of the drive device (AV) and of the transmission system (US). The closing device (SV) also comprises a force transmission spring unit (KUFE) that is configured to pick up the drive force transmitted from the drive device (AV) to the closing body (SK). The force transmission spring unit (KUFE) has a force transmission spring rate (FRKUFE) that is lower than the closing system spring rate (FRSLS).
