Description of the Related Art Conventionally, as a technique capable of avoiding a direct collision between a side wall of a vehicle body such as a door deformed by an impact load and a seated occupant in the event of a side collision of a vehicle, for example, Japanese Patent Laid-Open Publication No. There is a thing as shown in the gazette. That is, an airbag that inflates in a direction perpendicular to the vehicle body side wall or in a direction toward a space between the seated person and the vehicle body side wall side is provided on a seat back side portion facing the vehicle body side wall side.
Here, the airbag has a relatively large diameter in the inflated state, and is formed so as to largely inflate toward the side of the seated person. In addition, the door that has been deformed toward the interior of the vehicle due to the impact load has a shape in which the greatly inflated airbag is further pressed against the occupant.

物への三次衝突の増加を招くという問題点があった。However, in such a conventional technique, in the case of a side collision, the door is deformed so as to enter the interior of the vehicle due to the impact load, so that it bulges at the side of the seat back. The airbag may be strongly pushed toward the interior of the vehicle and come to the seated person with vigor. In this case, there is a problem that the reaction force received by the seated person from the airbag becomes large, and the seated person's inertia force at the time of collision cannot be effectively absorbed. Also,
The reaction force received by the occupant from the airbag causes an increase in tertiary collision with a vehicle interior such as a console adjacent to the side of the seatback near the vehicle interior.

いる。The present invention has been made in view of such a conventional problem. In the event of a side collision of a vehicle, a space in which the airbag can inflate is secured to prevent a seated person from receiving the airbag. Power can be suppressed and the inertial force applied to the occupant can be effectively absorbed, preventing a secondary collision of the occupant against the side wall of the vehicle body, and preventing a tertiary collision of the occupant with the vehicle interior. It is another object of the present invention to provide a vehicle safety seat capable of reliably improving the safety of a seated person.

Detecting an abnormal impact at the time of a side collision with the door 12,
A sensor 51 for instructing to inflate the side collision airbag 40 provided on the outer projection 21a is provided. The sensor 51 generally has three types: an electromechanical type, a mechanical type, and an electronic type. For example, in the case of the electromechanical type, when a steel ball in a cylindrical cylinder receives an impact, it shakes off the force of a magnet and jumps forward, and a current flows through the steel ball to a contact. The sensor 51 is connected to the inflator 44 via a signal line so as to output a signal to the inflator 44 upon receiving an impact force equal to or more than a predetermined value.

得る空間が確保される。Next, the operation will be described. When another vehicle collides with, for example, the door 12 on the driver's seat 20A side and a side collision of the vehicle occurs, the door 12 tries to enter the vehicle interior while being deformed by the impact load. However, since the door 12 that is about to be deformed toward the interior of the vehicle collides with the outer protruding portion 21a at one end of the upper part of the seat back 21 of the driver's seat 20A, entry of the door 12 into the interior of the vehicle is suppressed as much as possible. Therefore, a living space for the occupant is ensured, and the door 12
Between the side and the side end line, the outer protrusion 2
A space where the side collision airbag 40 provided in 1a can sufficiently swell is secured.

The sensor 51 that has detected the impact is connected to the outer protrusion 21.
A signal is output to the inflator 44 of the airbag device 41 provided in a. And the inflator 44
In this case, a chemical reaction takes place using a signal as a trigger to generate gas, and the side collision airbag 40 is instantly inflated. As shown in FIG. 1, the side collision airbag 40 can easily move the head of the occupant in the space secured between the door 12 and the side end line, particularly within the width of the space. It bulges to correspond to the sides of the neck and chest.

There is no possibility that the seated person will be strongly pushed toward the seated person and come to the seated person vigorously, and the seated person will not receive an excessive reaction force from the airbag 40. Thereby, the side airbag 40 swells to cover the head and chest of the occupant from the side.
Thereby, the impact force from the door 12 side can be sufficiently reduced, and the secondary collision of the seated person with respect to the door 12 side can be prevented while effectively absorbing the inertial force applied to the seated person. . Further, it is possible to effectively prevent the occupant from tertiarily colliding with a vehicle interior such as a console at the other end of the seat back 21.

The living space near the occupant's chest is sufficiently secured. It should be noted that the other vehicle is located on the door 12B on the passenger seat 20B side.
In the case where the vehicle collides with the vehicle and a side collision occurs, the safety of the occupant is reliably and sufficiently secured as described above.

が確実に向上する。According to the vehicle safety seat according to the present invention, the upper part of the seat back partially extends to the side of the vehicle body side wall so as to be close to the vehicle body side wall, so that a side collision can be prevented. In this case, a projecting portion for suppressing entry into the cabin on the side wall of the vehicle body and securing a space between the side wall of the vehicle body and one end of the seat back is formed, and the projecting portion is formed on the projecting portion in the event of a side collision. Within the width of the reserved space,
Since the side-impact airbag which inflates corresponding to at least the side of the head and chest of the seated person is provided, the inflated side-impact airbag is pushed more strongly than the side wall of the vehicle body and vigorously faces the seated person. It does not come and the occupant does not receive excessive reaction force from the airbag. Therefore, the inertia force of the seated person at the time of the side collision can be effectively absorbed and reduced, and the head and the chest of the seated person can be prevented from the secondary collision with the side wall of the vehicle body. It is also possible to effectively prevent the occupant from tertiarily colliding with a vehicle interior component such as a console on the other end side of the seat back, and the safety of the occupant is reliably improved.
