Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a vehicle occupant restraint system which also serves as an operating portion of the vehicle.

(Problems to be Solved by Prior Art and Invention) Generally, a seat belt is provided on a seat of a vehicle for the purpose of protecting an occupant in a collision. As such a seat belt, a three-point type seat belt is heavily used. That is, a three-point type seat belt is known in which the belt is rotated around the waist and shoulders of an occupant and each belt is fixed at one point.

However, when such a three-point seat belt is mounted on a vehicle, it is necessary to provide a space for storing the seat belt and a belt winding device when the seat belt is not used, and the seat belt has no parts. Since there are many points, there is a problem that the assembly process is complicated.

On the other hand, an instrument panel is arranged in front of the driver's seat, and a steering wheel projects from the instrument panel toward the driver's seat.
Therefore, the steering wheel and the instrument panel are an obstacle when the driver gets on and off the vehicle. Furthermore,
Since the various operation switches are arranged on the instrument panel, there is also a problem that the operability of the various switches is not sufficiently good depending on the body shape of the driver.

The present invention has been made in view of the above-mentioned conventional problems, and the steering wheel and the instrument panel do not interfere with the riding of a driver, and the operability of various operation switches is not affected by the body shape. An object of the present invention is to provide an occupant restraint device that also serves as a travel control member.

(Means for Solving the Problems) According to the vehicle occupant restraint system of the present invention, in order to achieve the above-mentioned object, according to the vehicle occupant restraint device, the pillar is erected on the floor behind the driver's seat of the vehicle and the upper end of the pillar is rotated. A pair of left and right restraint members which are attached so that they are substantially S-shaped when viewed from the side of the vehicle and are made of a shock-absorbing material, and the tips of the substantially S-shaped restraint members are provided. And a steering mechanism for controlling the steering angle of the vehicle, each of which is attached to the tip so as to be swingable to the left and right of the vehicle.

(Operation) After the occupant is seated in the driver's seat, the restraint member flipped up rearward is rotated forward to attach the restraint member to a region extending from the shoulder to the trunk of the occupant. At the tip of this restraint member, that is, at the position near the occupant, an operating member provided with a travel control member necessary for vehicle travel control is attached. Perform various operations.

Embodiment An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

1 to 4 show a state in which a vehicle occupant restraint system of the present invention is attached to a driver's seat, and the occupant restraint system 1 is provided on both left and right sides of a headrest 3 arranged above a seat back 2a of a seat 2. Tube-shaped restraining members 4, 5 having a substantially S shape
And columns 7 and 8 which are erected on the floor 6 of the vehicle and which support rear end portions 4a and 5a of the seat back 2a of the restraining members 4 and 5, respectively.
And an actuator 9 connected to both the restraining members 4 and 5.

Specifically, as shown in FIG. 2, the respective end portions 4a, 5a of the restraint members 4, 5 are rotatably attached to the upper ends of the columns 7, 8. Further, both ends of the cross member 10 are fixed to the positions near the ends 4a, 5a of the respective restraining members 4, 5, so that the respective restraining members 4, 5 are integrally connected. An actuator 9 is interposed between the floor 6 and the center of the cross member 10. The actuator 9 includes a cylinder 9a rotatably mounted on the floor 6 and the cylinder 9a.
The piston 9b is slidably fitted into the inside and has an end fixed to the cross member 10. Restraint member 4,
Reference numeral 5 denotes a flexible pipe 41 (51) made of a shock absorbing material and the flexible pipe 41 as shown in FIG.
The travel control member 13 is composed of a pad 42 (52) covering the (51), and a hollow bellows portion 11 (12) is provided at the tip thereof.
(14) is provided.

The traveling control member 13 (14) has various operation functions, such as a flip-up function of the restraining members 4 and 5, a vehicle steering function,
Various operation functions such as a brake function, a wiper operation function, a window washer operation function, and a light operation function can be provided as required. Specifically, as shown in FIG. 4, for example, the brake lever 15 is attached to the travel control member 13 on the left side of the occupant, and the travel control member 13 is indicated by an arrow in the figure with the bellows portion 11 as a fulcrum. The steering angle is changed by swinging to the left and right.
By configuring the traveling control member in this way, conventionally,
Since it is possible to omit the steering wheel that is formed so as to project from the front of the driver's seat, there is an advantage that there is no obstacle when the occupant is boarding and a space is provided in the driver's seat. Further, since the horn pad steering shaft and the like are not provided, the safety at the time of collision is improved. Wiring 16 such as various operation levers and operation switches arranged on the travel control members 13 and 14 passes through the hollow portion of the bellows portion 11 (12) and the flexible pipe 41 (51), respectively, and a control device (Fig. Connected (not shown). Also, the shift lever,
The brake lever and the like are of the so-called fly-by-wire type.

The operation will be described below.

When the occupant is not seated in the driver's seat, the restraint members 4 and 5 are in a state of being flipped up behind the seat 2 as shown by a chain double-dashed line in FIG. After the occupant sits on the seat 2, one or both of the upper rear restraint members 4 and 5 are gripped and pulled forward to the position shown by the solid line in FIG. The restraint members 4 and 5 are mounted at predetermined positions by rotating the ends 4a and 5a forward.
At this time, the cylinder 9a of the actuator 9 rotates forward around the mounting position on the floor 6, and the piston 9b extends upward from the cylinder 9a.

After the restraint members 4 and 5 are attached, various operations of the vehicle are performed by operating the travel control members 13 and 14 attached to the tips of the restraint members 4 and 5. Then, at the time of getting off the vehicle, the restraint members 4, 5 arranged on either of the traveling control members 13, 14
By operating the flip-up switch (not shown), the restraining members 4 and 5 are flipped up to the rear position of the seat 2 shown by the chain double-dashed line in FIG. At this time, the actuator 9 rotates to the position shown by the chain double-dashed line in FIG. 1, and the piston 9b is housed in the cylinder 9a.

(Effects of the Invention) As described above, according to the vehicle occupant restraint system of the present invention, the pillar that is erected on the floor behind the driver's seat of the vehicle and the rotatably attached to the upper end of the pillar are provided. Formed from a shock-absorbing material that is substantially S-shaped when viewed from the side,
A pair of left and right restraint members, and each restraint member,
Since each of the substantially S-shaped restraining members is configured to have a steering mechanism for controlling the steering angle of the vehicle, which is attached to the distal end of the restraining member so as to be upward and swingable to the left and right of the vehicle, Since it can be easily mounted on an occupant, and the driver can perform various operations at the time of traveling of the vehicle by the traveling control member at the tip of the restraint member, the conventional instrument panel This eliminates the need for operation and prevents problems such as reduced operability due to the body shape of the driver.
