Embodiment Construction

[0020] The best mode for carrying out the present invention will be described below using the drawings.

[0021] figure 1 It is a diagram schematically showing a part of a pretensioner used as an example of an embodiment of the seat belt device of the present invention.

[0022] like figure 1 As shown, the pretensioner 1 used in the safety belt device of this example is a buckle pretensioner, and the outer cover (equivalent to the peripheral parts of the pulled part of the present invention) 3 that can expand and contract in the axial direction is installed on the bracket 2 , the other end of the cover 3 is attached to a well-known buckle (corresponding to the pulled member of the present invention) 4 . This buckle 4 is an existing known buckle, and its upper end is provided with a tongue insertion opening (not shown). Metal wire 5 is hung on the pulley 6 that is located at belt buckle 4 lower end sides (opposite side of tongue insertion opening), and one end of this wire 5...

Abstract

In order to manufacture a kinetic energy absorbing member of simple shape at low cost which absorbs the kinetic energy of a pull-in member such as a buckle or a lap anchor when reaching the bottom, the kinetic-energy absorbing member (15) is composed of a thin-walled oval tubular member which is made of metal such as iron or aluminum. The kinetic-energy absorbing member (15) is arranged between a bracket and buckle such that the axial direction of the kinetic-energy absorbing member is equal to the pulling direction of the buckle. A wire (5) forms a U-turn about a pulley (6) of the buckle (4) so as to have two wire portions (5a, 5b) which extend through the inside of the tubular kinetic-energy absorbing member (15). As the pretensioner is actuated, the buckle is pulled with the wire (5) so as to depress the kinetic-energy absorbing member (15) with the bracket so that the kinetic-energy absorbing member (15) collapses, thereby absorbing the kinetic energy of the buckle when reaching the bottom.

Description

technical field [0001] The present invention relates to, for example, the technical field of seat belt devices attached to vehicle seats such as automobiles, and particularly relates to the technical field of the following seat belt devices: the seat belt is tensioned by operating a pretensioner in an emergency such as a vehicle collision , improve the restraint of the occupants. Background technique [0002] In the past, a seat belt device was attached to the seat of a vehicle such as a car. When the vehicle decelerates greatly in an emergency such as a vehicle collision, the seat belt device restrains the occupant's inertial movement by using the seat belt to protect the occupant. crew. Among such existing seat belt devices, there is a seat belt device equipped with a pretensioner, wherein the pretensioner tightens the seat belt in the above-mentioned emergency to improve restraint, and restrains the seat belt quickly and with a large restraint force. crew. A convention...
