Sport D1Spec 4-point seatbelts.
Belt width - 2 "
Clasp on the hip buckle.
After fastening, they partially protect against body injuries in the event of collision or sudden braking of the car.
The close connection of passengers to the car's cabin skeleton creating a safety cage with tight-fitting seatbelts allows vehicle users to lose speed during a collision with the car.
As a result, the accelerations (delays) acting on them are lower. Passengers are "bound" with the cabin with a 4-point seat belt.
