車両用シートベルト装置をさきに開発した。[Detailed Description of the Invention] The present invention relates to a seat belt device installed in the seats of various vehicles. Normally, the base side of the seat belt installed in a vehicle seat is attached directly to the seat frame, so the seat frame lacks the strength to support the belt against strong external forces applied to it in the event of a collision, etc. If the rigidity of the seat frame is increased to resist the external force, the weight of the seat will increase significantly and the cost will increase.In addition, the external force may deform or damage the slide rail, impairing sliding performance. In order to overcome these drawbacks, a vehicle seat belt device as shown in FIGS. 1 and 2 was developed.

ンａ上に延出させた構造になつている。 As shown in FIGS. 1 and 2, the vehicle seat belt device is configured such that a seat cushion a having a seat bag b disposed at the rear is connected to front and rear fixed brackets d and d via a slide rail c consisting of an upper rail and a lower rail. In the slideable seat mounted on the floor f, the toothed rail 3 is mounted on the floor f below the seat cushion a by the front and rear support brackets 1 and the fixed bracket 2, and is oriented in the longitudinal direction of the vehicle body. A belt mounting bracket 5 is provided, the upper part of which is fixed to the seat frame 4, and the toothed rail 3 loosely inserted into the lower locking hole 5a. The belt 6 is fixed to the upper part of the belt mounting fitting 5 with rivets 7 or the like, and extends above the seat cushion a from between the rear part of the seat cushion a and the lower part of the seat bag b.

る。 However, the vehicle seat belt device is advantageous in that it has a structure in which the toothed rail 3 on the floor side mainly receives the strong external force applied to the belt 6 via the belt mounting bracket 5. Due to the traction force from the belt 6, the lower part of the belt mounting bracket 5 is deformed in the direction of the arrow B, so that its engagement hole 5a is always locked to the toothed rail 3, improving the sliding performance of the seat. is lowered. When a strong external force is applied to the belt 6 during a collision or the like, the upper part of the belt mounting bracket 5 is detached from the seat frame 4, rotated in the direction of the arrow C, and pulled upward.
Since the locking hole 5a is locked to the toothed rail 3, the amount by which the belt 6 is pulled out increases and the locking is delayed.

されて、シートベルト機能が大幅に向上される。 The present invention relates to the invention of a vehicle seat belt device developed in view of the above-mentioned circumstances, and is a vehicle seat that is supported by a slide rail, moves only in the longitudinal direction of the vehicle body, and is locked at an appropriate position. , a belt mounting bracket having an upper end fixed to the seat frame and a locking hole formed in the lower part; and a lower side of the seat cushion on the inside of the slide rail that is loosely inserted into the locking hole and extends along the longitudinal direction of the vehicle body. a toothed rail disposed on the floor of the vehicle and having both ends fixed to the floor; a belt fastening fitting fixed to the intermediate portion of the belt fitting; and a toothed rail fixed to the seat frame side and having both ends fixed to the floor; The seat frame is characterized in that it includes a rotating support pivotably connected between the fixing part of the belt fastening metal fitting and the locking hole, and is movable only in the longitudinal direction of the vehicle body by a guide rail. The upper end of the belt mounting bracket is fixed to the seat frame, and the middle part is pivotally connected to the rotating support fixed to the seat frame, and the belt fixing bracket is pivotally connected to the upper end of the belt mounting bracket and the rotating support. Since it is attached to the belt mounting bracket between the middle part of the belt and the belt mounting bracket, the input from the belt clamping bracket is distributed to both and efficiently transmitted to the seat frame, reducing the weight and cost of the belt mounting bracket and rotating support. In addition, since the toothed rail is placed on the floor below the seat cushion on the inside of the slide, the toothed rail does not protrude to the side of the seat cushion and there are no protrusions on the side of the seat cushion, resulting in an aesthetically pleasing appearance. Along with improvements, safety can also be improved.
Furthermore, when a strong external force is applied to the belt in the event of a collision, etc., the upper part of the belt mounting bracket is detached from the seat frame and rotated. Since the central part is supported and rotated around this part, the rotational deviation of the upper and lower parts of the belt mounting bracket is significantly reduced, and the locking hole is immediately locked to the toothed rail, reducing the amount of belt pullout. In addition to faster locking, strong belt support strength is achieved by the rotary support along with the toothed rail on the floor side, and the support strength of the guide rail and the strong strength of the toothed rail with both ends supported on the floor are increased. This supporting force ensures sufficient supporting force against the strong external force, and the seat belt function is greatly improved.
