Abstract: Disclosed are a pretensioner and a safety belt assembly including the same. The pretensioner includes an internal cylinder movably installed within an external cylinder with an outer surface thereof in contact with an inner surface of the external cylinder, a piston installed in the internal cylinder, a retracting member configured with one side connected to the piston and the other side configured to extend from the external cylinder and connected to a belt fastening a passenger, a gas generator configured to supply gas to the inside of the external cylinder to move the piston in a direction of pulling the retracting member, and a one-way restriction device configured to allow the piston to move with respect to the internal cylinder when the piston moves in the direction of pulling the retracting member and to restrict the piston to be within the internal cylinder when the piston moves in reverse direction.

Abstract: The present invention provides push-pull type tilt lever assembly for a steering system of a vehicle. According to the push-pull type tilt lever assembly for a steering system of a vehicle, a tilt lever assembly is disposed at the upper portion of a side of a steering column to perform locking and unlocking in tilt and telescopic functions in the steering system and achieves tilt locking and tilt unlocking by pushing or pulling a tilt lever. Further, since tilt lever is disposed at the upper portion of a side of steering column, it does not contact with the driver's knees in a car crash, such that it is possible to reduce driver's knees injury rate and remove cause of demerit for the knees injury rate in accordance with EURO NCAP that is a European car safety performance assessment programme.

Abstract: A method of assembling a cover of a steering wheel, includes a) punching the cover, in which first and second series of sewing holes are formed at both lateral sides of the cover, b) sewing the first and second series of the sewing holes of the cover with a first thread and a second thread respectively to form first and second crossing holes in each series of the sawing holes, c) wrapping the cover around a rim of the steering wheel, d) inserting a third thread to pass the first and second crossing holes in common, e) fastening lower ends of the first, second and third threads, f) pulling upper ends of the first and second threads upwards sufficiently enough to remove a gap formed between both the lateral sides of the cover, and g) fastening the upper ends of the first, second and third threads.
