Description

[Detailed Description of the Invention] This invention relates to a high back seat that can be attached to a child seat, and more particularly to a high back seat that can securely hold a child seat.

As a conventional high back seat, there is one shown in FIG. 1, for example.

In the figure, reference numeral 1 denotes a seat cushion of a high-back seat. A seat back 2 is provided at the rear end of the seat cushion 1 so as to be tiltable.

The seat back 2 has a headrest bracket 4 which is a pressed flat plate connected to the upper end of the back frame 3 by welding, the back frame 3 and the headrest bracket 4 are wrapped with a pad 5, and the outer surface of the pad 5 is covered with a skin 6. It is formed by

In such a conventional high back seat, when attaching the child seat 7 to the high back seat, the child seat 7 is first placed on the seat cushion 1, and the lap belt 9 attached to the floor 8 is attached to both sides of the seat of the child seat 7. It is inserted into each locking hole 7a and fixed.

Next, the child seat 7 fixed to the seat cushion 1 has one end fixed to the rear position of the high back seat on the floor 8 through the belt locking hole 7b provided at the upper part of the child seat 7, and the child seat 7 is placed over the upper edge of the seat back 2. The other end of the support belt 1o is moored and fixed to the high back seat. However, in conventional high back seats, the child seat 7 is fixed to the high back seat and when in use, the child seat 7 Support belt 10
is simply wrapped around the upper edge of seat back 2,
There is a risk that the child seat support belt 10 may shift laterally due to vibrations of the vehicle body or careless contact with the child seat back 2, and may slip off the upper edge of the seat back 2. The problem was that it lacked certainty.

In addition, the headrest bracket 4 built into the upper part of the seatback 2 is designed to have a moderate strength without being too strong, in order to reduce the impact on the head of the occupant sitting in the high-back seat in the event of a vehicle collision. It is made of a material that can be deformed.

Therefore, if the vehicle is in a collision while the child is secured in the child seat 7 with the child lap belt 7c, the child seat 7 moves forward of the seat back 2 and the child seat support belt is attached to the upper edge of the seat back 2. 10 applies a downward impact load, and the headrest bracket 4 built into the upper part of the seatback 2 receives the impact load and deforms, causing the upper edge of the seatback 2 to collapse as shown by the two-dot chain line in FIG. There was also the problem that it would bend forward.

This idea was created by focusing on these conventional problems.A gap is provided between the headrest bracket and the upper end of the high back frame, and an anchor is attached to the surface of the headrest through the gap and attached to the floor behind the seatback. A guide hole is provided through which a child support belt with one end fixed is inserted, and the gap and guide hole allow the child seat support belt to pass through the seat back in the front and back direction, and the upper edge of the back frame allows the child seat support belt to pass through the middle part of the child seat support belt. The purpose is to solve the above problems by supporting the .

This invention will be explained below based on the drawings.

FIGS. 2 to 4 are diagrams showing an embodiment of this invention.

In the figures, parts or members that are the same or equivalent to those of the conventional example are given the same reference numerals and redundant explanations will be omitted.

In the figure, the headrest bracket 4 is cut out at the center of the connecting part 11 between the upper end of the back frame 3 and the headrest bracket 4, so that the upper end of the back frame 3 is inserted through the upper part of the pad 5, but most of it is partially exposed. A gap 12 is formed.

In addition, a connecting portion 1 is provided between the pad 5 and the outer skin 6 of the seat back 2.
A horizontal linear child seat support belt insertion guide hole 13 passing through the gap 12 and penetrating the seat back 2 in the front-rear direction is formed at a portion corresponding to the gap 12 in FIG.

Annular finishers 14 are fixed with adhesive to the opening edges at both ends of the child seat support belt insertion guide hole 13.

In the figure, reference numeral 15 denotes a spring installed horizontally on the back frame 3.

The child seat 7 having a child lap belt 7c is fixed to the seat cushion 1' by a lap belt 9 whose both ends are fixed to a floor 8 provided on the side of the seat cushion 1, and a belt locking hole 7b in the upper part. A child seat support belt 10 whose one end is fixed (child seat fixing point C) is inserted through the gap 12 and the guide hole 13, and its intermediate portion 10a is attached to the upper edge 3a of the upper end of the frame 3 directly or via a finisher 14 or the like. The other end 10b is fixed to the seat back 2 by being fixed with a bolt or the like (floor fixing point a) to an anchor 10C provided on the floor 8 at the rear of the seat back 2.

Next, the action will be explained.

When attaching the child seat 7 to the high back seat, place the child seat 7 on the seat cushion 1, fix it to the seat cushion 1 with the lap belt 9, and then guide the child seat support belt 10, which is fixed at one end to the rear position of the high back seat on the floor 8. Hole 1
3, and the other end of the child seat support belt 10 is anchored to a belt locking hole 7b provided in the upper part of the child seat 7, whereby the child seat 7 is fixedly attached to the seat back 2.

The child seat 7 is installed in this way and is fixed.
The child is seated in the seat, and the child is secured using a child lap belt 7c provided in the child seat 7.

While driving in such a state, even if the child seat support belt 10 or the child seat 7 is vibrated by the vehicle body or inadvertently comes into contact with the occupant, the child seat support belt 10 will pass through the gap 12 and close to the seat back. Since the child seat support belt is inserted into the child seat support belt insertion guide hole 13 that passes through the child seat back 2 in the front-rear direction and is guided and locked, it will not come off from the seat back 2 due to lateral displacement.

Furthermore, if the child seat 7 moves forward of the seat back 2 due to a collision of the vehicle while the vehicle is traveling in a similar condition, the child seat support belt 10's floor fixing point a1 seat support point shown in FIG. ri1 China leaf sheet fixing point C tries to be in a straight line.

Since the upper edge 3a of the upper end of the back frame 3 is partially exposed within the gap 12, the child seat support belt 10 applies a load pushing down the exposed upper end of the back frame 3, but the back frame 3 has sufficient strength. Because of this, it can withstand this load sufficiently and will not deform.

In this embodiment, the headrest bracket 4 is cut out at the center of the connection part 11 between the headrest bracket 4 and the upper end of the back frame 3, and the upper end of the back frame 3 is partially exposed, or a gap 12 is created through a skin pad or finisher. However, it goes without saying that the gap 12 may be formed by connecting the lower end of the headrest bracket 4 to the back frame 3 having a recess at the upper end.

As explained above, according to this invention, the configuration is such that a gap is provided between the headrest bracket and the upper end of the back frame, and one end is attached to the outer skin, and one end is attached to the anchor provided on the floor behind the seat back through the gap. A guide hole is provided through which a child seat support belt with a fixed child seat is inserted, and the gap and guide hole allow the child seat support belt to pass through the seat back in the front and back direction, and the upper edge of the back frame supports the middle part of the child seat support belt. I let it happen.

Since the high-back seat is used, the child seat support belt can be inserted into the guide hole to fix the child seat to the high-back seat, so the child seat can be securely held without the belt coming off, and the safety of the child can be ensured.

With this high back seat, there is no risk of deformation since the back frame receives a large load, and there is no need to reinforce the headrest bracket, so the weight can be reduced compared to conventional seats.
