Abstract
A seatbelt apparatus includes an electric motorfor winding a seatbelt, and a microcomputerfor controlling the electric motor. The microcomputercontrols the electric motorso as to wind the seatbeltat a winding load which increases to a first winding load at a first rising gradient when collision is detected using a detected length and a detected vehicle velocity by a length sensorand a vehicle velocity sensor. The microcomputercontrols the electric motorso as to wind the seatbeltat a winding load which increases to a second winding load which is larger than the first winding load at a second rising gradient which is larger than the first rising gradient when an emergency braking operation is detected by detection signal from a brake switch. Therefore, the seatbelt can be wound at a winding mode and a winding load which can protect a passenger without giving much feeling of discomfort.
