BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile rear seat structure having a slit for passing a lower seat belt.

[0002]

2. Description of the Related Art For example, as a rear seat of a one-box car, a bench type rear seat 1 is used, as shown in FIG. 2, in which a plurality of passengers can sit side by side. The rear seat 1 includes a seat cushion 2 and a seat back 3 provided at a predetermined angle on the rear end side of the seat cushion 2 in the front-rear direction.

When the seat back 2 is for seating two people, for example, a slit 4 having an open rear end is formed in the central portion in the longitudinal direction. As shown in FIG. 3, one end of a pair of lower seatbelts 8 having one end fixed to a floor 6 via an anchor plate 5 and the other end provided with a buckle 7 is inserted into the slit 4. The buckle 7 has
An upper seat belt 9 for holding the upper half of the occupant, which is indicated by a chain line in FIG. 4, is detachably connected.

A frame line 11 is built inside the seat back 2 along the peripheral portion. At a portion of the frame line 11 corresponding to the slit 4, a bent portion 12 having a concave shape along the shape of the slit 4 is formed as shown in FIG.

A cushion material 13 is provided on the upper surface side of the frame line 11 as shown in FIG. 3, and the cushion material 13 is covered with an exterior material 14.

Conventionally, both sides of the bent portion 12 have been formed by straight portions 12a along both sides of the slit 4.
Therefore, when the upper seat belt 9 is attached to and detached from the buckle 7, the lower seat belt 8 is repeatedly subjected to a force in the direction indicated by the arrow B. When a force in the direction indicated by the arrow B is applied to the lower seat belt 8, a force in the direction indicated by the arrow C is generated at the portion of the lower seat belt 9 that is in contact with the slit 4. Therefore, the middle portion of the lower seat belt 8 may shift toward the open end side of the slit 4 and finally come off from the slit 4.

[0007]

As described above, when a force is applied to the lower seat belt that has been conventionally passed through the slit of the seat back, the middle portion of the lower seat belt sometimes comes off the slit. It was

The present invention has been made in view of the above circumstances, and an object of the invention is to provide a rear seat structure for an automobile in which the lower seat belt is prevented from coming off from the slit even when a force is applied to the lower seat belt.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a seat cushion of a rear seat with a slit opened at the rear end in the front-rear direction thereof, and one end of which is fixed to the floor. The middle part of the lower seat belt with a buckle at the end is passed through, and a frame line is arranged inside the seat cushion, and a concave bent portion is formed at a portion of the frame line corresponding to the slit. In the rear seat structure described above, the bent portion of the frame line includes an inclined portion that is inclined outward in the width direction of the slit toward the open end side of the slit, and an inward portion in the width direction of the slit at the tip of the inclined portion. It is characterized in that a protrusion protruding toward the front is formed continuously.

[0010]

According to the above construction, even if the upper seat belt is displaced toward the open end side of the slit, the protrusion formed on the frame line prevents the upper seat belt from coming off the slit.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIG. Note that the same parts as those in the configuration shown in FIG.

That is, this invention differs from the structure shown in FIG. 4 in the shape of the bent portion 22 formed in the portion of the frame line 21 corresponding to the slit 4. The bent portion 22 of the present invention is formed on both sides corresponding to the slit 4 in an inclined portion 22a inclined outward in the width direction toward the open end side of the slit 4.

A projecting portion 22b protruding inward in the width direction of the slit 4 is continuously formed at a portion corresponding to an open end portion of the slit 4 which is a tip of each of the inclined portions 22a. Further, since the inclined portion 22b is inclined outward in the width direction of the slit 4, it is possible to form the protruding portion 22b at the outermost tip end portion without protruding into the slit 4. That is, it is possible to make the protrusion size of the protrusion 22b from the tip of the inclined portion 22a inward in the width direction of the slit 4 sufficiently large so that the lower seat belt 8 does not come off from the slit 4.

According to the seat back 2 having such a structure, the passenger sits down and the buckle 7 of the lower seat belt 8 is seated.
By detaching and attaching the upper seat belt 9 to the lower seat belt 8, a force is generated in the lower seat belt 8 in the direction of pushing and opening the slit 4 shown by the arrow B.

Thus, when the force in the direction of arrow B is generated,
The lower seat belt 8 slides toward the open end side along the inner surface of the slit 4 indicated by the arrow C. When the lower seat belt 8 slides to the open end of the slit 4, the lower seat belt 8 is caught by the protrusion 22b of the bent portion 22 formed in this portion. Therefore, even when a force in the direction indicated by the arrow B is applied to the lower seat belt 8 when the upper seat belt 9 is detached, the lower seat belt 8 is prevented from coming off the slit 4.

In the above-mentioned one embodiment, the case where the structure of the present invention is applied to the rear seat for two people has been described, but the present invention can be applied to the rear seat for three or more people. When the seat back of the rear seat is for three persons, two slits are formed in the seat back, and a bent portion formed of an inclined portion and a protruding portion is formed at a portion corresponding to each slit of the frame line, as in the above-described embodiment. Should be formed.

[0017]

As described above, according to the present invention, the inclined portion and the projection continuous to the tip of the inclined portion are formed in the portion of the frame line provided on the seat cushion corresponding to the slit through which the lower seat belt is passed. The bent portion composed of the parts is formed.

Therefore, even if the lower seat belt moves along the slit, the lower seat belt is caught by the protrusion, so that it can be prevented from coming off the slit. Moreover,
Since the protruding portion is formed continuously with the inclined portion, the protruding size of the protruding portion from the tip of the inclined portion can be made sufficiently large so that the lower seat belt can be easily caught.
