Description

[0001] Safety belt for rear-seat [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt of a rear seat for a passenger car, in particular, a seat belt that can be most suitably applied to a middle seat of a rear seat, and more particularly, So that the webbing can be prevented from covering the face or the neck of the passenger.

The seat belt of the vehicle is a safety device for preventing the occupant from colliding with the inside of the car or bouncing out of the car due to impact energy in the event of a vehicle accident.

The speed of the vehicle in which the collision occurs in the vehicle sharply decelerates, but the inner occupant moves forward by the inertia. The seatbelt restrains the occupant's body by preventing the webbing from colliding with the occupant (with internal parts of the vehicle) and bouncing outside when a collision occurs.

The general structure of the seat belt includes a webbing formed into a flat strip shape having a predetermined length and a buckle fastened to a tongue attached to the webbing; And a belt anchor (also referred to as a retractor) that enables the length of the webbing to be adjusted and prevent loosening of the webbing when a collision occurs.

The seat belt is designed to instantaneously restrain the webbing at the belt anchor when an occupant senses an impact after being worn to securely secure the body of the occupant to the seat of the vehicle, but also to endure the inertial load several times to several tens of times the weight of the occupant.

The seat belt is widely used for the two-point type that restrains only the waist according to the manner of mounting the webbing, and the three-point type that restrains the waist as well as the upper body of the occupant. The two-point system is commonly used in passenger seats of large buses, and the three-point system, which protects passengers relatively safely, is mainly used in passenger vehicles.

On the other hand, conventionally, even in a passenger car, a two-point seat belt is used in the rear seat (rear seat) behind the seat, but a three-point seat belt is also applied to the rear seat of a passenger car in order to amend the regulations and ensure the safety of the passenger.

Referring to FIG. 1, the three-point type safety belt mounted on the rear seat is constructed such that the seat belts mounted on the left and right seats in the rear seat 2 configured to seat three persons are provided with belt anchors And webbing was hanged on each of the two side pillars. However, as shown in the drawing, the seat belt mounted on the middle seat is mounted in such a manner that a belt anchor (not shown) is laid on the roof panel 3 of the vehicle body so that the webbing 1 extends upward.

That is, the buckle 4 is fixedly mounted on the rear seat between the backrest portion 2b and the seat portion 2a, and one end of the webbing 1 is separated from the backrest portion 2b by the buckle And the other end is connected to the belt anchors embedded in the roof panel 1. [0033]

However, in the case where the fastening position of the tongue 5 and the buckle 4 is fixed and the webbing 1 is led to the roof panel 3 as in the conventional structure, There is a problem that the passenger on the middle seat 1 or the passenger on the side seat (right side in Fig. 1) partially covers or covers the face or neck.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a seat belt for a rear seat capable of eliminating the problem of covering the face of a passenger even if the seat belt is mounted on the middle seat of the rear seat.

According to another aspect of the present invention, there is provided a seat belt of a rear seat including a seat portion and a backrest portion coupled to the seat portion from behind, wherein the seat portion is seated on a floor panel, A webbing having one end connected to the seat portion and spaced apart from the buckle and the other end disposed to extend rearward beyond the upper end; And a belt anchor which is mounted on the floor panel at a rear side of the backrest and is coupled to the webbing so that the webbing is wound inside, thereby enabling the webbing to be unwound and rewound and fixed.

A clip is mounted on the upper end of the backrest so that the webbing slides inside. When the belt anchor is mounted on the mounting groove, the cover having the guide hole formed therein is coupled to cover the mounting groove so that the webbing can be inserted and removed.

In addition, a belt cover is provided on the back side of the backrest so that the webbing is arranged close to the back surface of the backrest.

According to the present invention having the above-described structure, since the belt anchor connected to the webbing is mounted on the floor panel, the problem of the conventional structure in which the webbing covers the face or the neck of the passenger can be solved.

A clip is attached to the upper end of the backrest portion of the rear seat so that the webbing can be prevented from flowing down or moving sideways and a belt cover is provided on the back side of the backrest portion so that the webbing does not cause friction with the vehicle body, There is an effect that can be brought close to this part.
