Japanese Unexamined Patent Publication No. 2006-0442885

However, in the conventional pedestrian protection device, the airbag as a receiving member that receives and protects the pedestrian may come into contact with the road surface and be damaged before the pedestrian is received, and if damaged, Since the expansion gas is discharged, it causes a situation in which pedestrians cannot be protected.

The present invention solves the above-mentioned problems, and provides a pedestrian protection device capable of preventing damage due to contact with a road surface before receiving a pedestrian by a receiving member that receives and protects a pedestrian. The purpose.

The pedestrian protection device according to the present invention is a pedestrian protection device mounted on the side surface side of the vehicle and capable of protecting pedestrians falling on the road surface side after the primary collision.
A receiving member that is extended from the side surface of the vehicle and is arranged between the road surface and the pedestrian so that the pedestrian can be received and protected during operation.
In addition to being composed of vehicle body side members arranged on the side surface side of the vehicle, it is possible to prevent the receiving member from coming into contact with the road surface before receiving pedestrians from the standby position on the side surface side of the vehicle. A cover material that is fed out to a feeding position located on the road surface side of the receiving member by rotationally moving the upper end side with the lower end side as the center of rotation.
An actuator that moves the cover material from the standby position to the feeding position side,
A stopper material that connects the cover material and the side surface side of the vehicle to stop the cover material at the feeding position.
It is characterized in that it is configured with.

In the pedestrian protection device according to the present invention, when activated, the cover material is moved from the standby position on the side surface side of the vehicle to the feeding position side by the actuator, and is stopped at the feeding position by the stopper material. At that time, the receiving member is also extended from the storage position on the side surface side of the vehicle and is arranged between the road surface and the pedestrian so that the pedestrian can be received. A cover material is provided on the road surface side of the vehicle so as to prevent the receiving member from coming into contact with the road surface before receiving the pedestrian. Therefore, since the receiving member before receiving the pedestrian is prevented from coming into contact with the road surface, it can smoothly receive and protect the falling pedestrian without being damaged from the road surface.

Therefore, in the pedestrian protection device according to the present invention, the receiving member that receives and protects the pedestrian can prevent damage due to contact with the road surface before receiving the pedestrian by the cover material, and can be smoothly operated during operation. , Can catch and protect pedestrians.

Then, in the pedestrian protection device according to the present invention, the receiving member may be an airbag that allows the expansion gas to flow in and is supported on the upper surface side of the cover material arranged at the feeding position.

In this case, if the airbag is covered with the cover material in the standby position and stored, the airbag can also be used as the actuator that moves the cover material from the standby position to the feeding position side when the expansion gas flows in. It is possible to reduce the number of component parts by eliminating the need to prepare a separate actuator.

Further, in the pedestrian protection device according to the present invention, the receiving member is composed of a flexible net and is suspended near the upper end of the cover material at the feeding position and on the side surface side of the vehicle. May be arranged.

In such a configuration, if the cover material moves from the side surface side to the lower end side of the vehicle to the standby position by the operation of the actuator, the net as a receiving member can prevent contact with the road surface. Above the road surface, it will be suspended so as to block between the vicinity of the upper end of the cover material at the feeding position and the side surface side of the vehicle, and a flexible space is provided on the lower side to provide cushioning properties. Arranged to do so. Therefore, the net as a receiving member can receive and protect the pedestrian who falls to the road surface side after the primary collision with good cushioning property. Further, in such a configuration, a pedestrian can be received by simply rotating the cover material during operation, and the receiving member made of a net can be deployed from the stored state. Therefore, the pedestrian protection device can be constructed more easily than in the case where the receiving member for which it is necessary to prepare an inflator (gas supply machine) for supplying the expansion gas or the like is composed of an airbag.

Further, when the receiving member is composed of a net, the cover material has an inverted U shape on the side surface side of the vehicle and receives a pedestrian in the central portion surrounded by the inverted U shape frame. If it is arranged as an inverted U-shape with a stoptable area arranged, the receiving member made of a net closes the central portion of the inverted U-shape in the cover material at the feeding position. It may be configured to feed out.

Even in such a configuration, if the cover material is placed at the feeding position by rotating the upper end side during operation, the net as a receiving member can prevent contact with the road surface, and is above the road surface. , It is drawn out so as to close the central portion of the cover material, and is arranged so as to have a cushioning property by providing a flexible space on the lower side. Therefore, the net as a receiving member can receive and protect the pedestrian who falls to the road surface side after the primary collision with good cushioning property. Therefore, even with such a configuration, since the receiving member can be composed of a net, compared with the case where the receiving member for which it is necessary to prepare an inflator (gas supply machine) for supplying expansion gas is composed of an airbag. , The pedestrian protection device can be easily configured.

Further, in the pedestrian protection device according to the present invention, the stopper material is connected to the length adjusting mechanism so that the length dimension for feeding out the cover material can be changed, and the length adjusting mechanism is said to be at the time of feeding. It is desirable that the stopper material is configured so as to adjust the length dimension according to the presence or absence of the receiving member or the allowable feeding space of the cover material.

In such a configuration, if there is an interfering object on the side of the vehicle and the allowable feeding space at the time of feeding the receiving member is limited, the cover material is determined in advance by adjusting the length adjusting mechanism. The stopper material adjusted to the length reduces the opening and feeds to the feeding position where the feeding space is reduced. Therefore, the receiving member that is delivered during operation can avoid interference with the interfering object before the pedestrian is received by the cover material, and can prevent damage due to contact with the interfering object. Therefore, the receiving member can be smoothly delivered after the primary collision. It can catch and protect pedestrians. Similarly, even when the allowable feeding space at the time of feeding the cover material is limited by the surrounding interference, the cover material is opened by the stopper material adjusted to a predetermined length by adjusting the length adjusting mechanism. Is reduced to a feeding position where the feeding space is reduced so as not to interfere with the interfering object. Therefore, the receiving member to be fed is interfered with the interfering object by the cover material avoiding the interference with the interfering object. Can be avoided and smoothly receive and protect pedestrians after the primary collision.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the pedestrian protection device S1 of the first embodiment is a pedestrian M that falls to the road surface R side after the primary collision. The receiving member 40 that can receive and protect the pedestrian, the cover material 20 that prevents the receiving member 40 from coming into contact with the road surface R before receiving the pedestrian, and the cover material 20 are extended from the standby position C0 to the extension position C1 side. It is configured to include an actuator 30 for feeding and a stopper material 60 for stopping the fed cover material 20 at the feeding position C1. Further, the pedestrian protection device S1 is configured to include a control device 80 for controlling the operation of the actuator 30, and a length adjusting mechanism 70 capable of adjusting the length of feeding out the stopper member 60.

The control device 80 inputs a signal from a collision detection sensor 82 including an acceleration sensor and a pressure sensor for detecting a primary collision, and detects (or predicts) a collision of the vehicle V with a pedestrian M. The actuator 30 is operated. The sensor 82 is arranged on a front bumper or the like of the vehicle V (not shown). Further, the control device 80 also receives a signal from a sensor 84 for detecting an interfering object, which is composed of a millimeter wave radar, an infrared radar, or the like capable of detecting an interfering object IV of another vehicle or the like existing around the side surface VS of the vehicle V. It is possible to input. Then, in the case of the first embodiment, when the control device 80 detects the collision of the vehicle V with the pedestrian M, the actuator 30 is activated and the control device 80 is brought into the vicinity based on the signal from the sensor 84 input in advance. If there is an interfering object IV that limits the allowable feeding space when feeding the receiving member 40, the operation of the length adjusting mechanism 70 is controlled to shorten the feeding length of the stopper material 60, and the feeding length of the stopper member 60 is shortened. If there is no interfering object IV that limits the allowable feeding space when feeding the receiving member 40, the stopper member 60 is controlled so as to be fed longer.

The actuator 30 of the first embodiment is an airbag 40 that also serves as a receiving member, and the airbag 40 expands and expands by an expansion gas supplied from an inflator 42 as a gas supply device during operation. It is extended from the side surface VS side of the vehicle V so as to receive and protect the pedestrian M, and is arranged between the road surface R and the pedestrian M.

Specifically, the airbag 40 has an expansion completed shape of a substantially rectangular plate shape, and the outer panel 3 and the inner panel 5 at each door 2 (F, B) of the front and the rear on the vehicle body (body) 1 side of the vehicle V. When the expansion gas from the inflator 42 flows in, the outer panels 3 are pushed open and protrude from the upper end 21 of each outer panel 3. Therefore, the airbag 40 at the storage position P0 before feeding is covered with the outer panel 3 and is stored on the side VS side of the vehicle V.

In the case of the first embodiment, the outer panel 3 composed of the vehicle body side members arranged on the side VS side of the vehicle V constitutes the cover material 20. That is, the cover material 20 can prevent the pedestrian M from coming into contact with the road surface R before being received by the airbag 40 as a receiving member when the pedestrian protection device M1 is operated, that is, by operating the actuator 30. , It is pushed out by the airbag 40 that expands as the actuator 30, and moves from the standby position C0 on the side VS side of the vehicle V to the feeding position C1 side. The cover material 20 made of the outer panel 3 is rotationally moved so that the lower end 22 side is centered on the hinge 4 arranged on the lower edge side of the door 2 (F, B) and the upper end 21 side is opened to the outside O of the vehicle. It moves from the standby position C0 on the side VS side of the vehicle body 1 to the feeding position C1 side in which the outer surface 24 is brought closer to the road surface R. When the cover material 20 is arranged at the feeding position C1, the cover material 20 is located on the road surface R side of the airbag 40 as a receiving member, and the airbag 40 is in contact with the road surface R before the pedestrian M is received. Prevent damage.

The stopper material 60 is arranged on the side surface VS side of the vehicle V, connects the upper end 21 side of the cover material 20 and the side surface VS side of the vehicle V, and stops the cover material 20 at the feeding position C1. The tip 60a side is connected to the upper end 21 side of the cover material 20, and the base 60b side is connected to the retractor 71 of the length adjusting mechanism 70 with the roller 72 interposed therebetween. The stopper material 60 is composed of a flexible string material and is arranged in four pieces, and the front and rear (front portion) on the upper end 21 side of each cover material 20 composed of the outer panels 3 of the front and rear doors 2F and 2B. The front end 60a side is connected to the 21a side and the rear portion 21b side, respectively, and the original portion 60b side is connected to the retractor 71.

The retractor 71 of the length adjusting mechanism 70 is adjusted by the control device 80 so that the length of feeding out the stopper member 60 can be adjusted in at least two stages of length (LL, LS). That is, when the control device 80 that has input the signals from the sensors 82 and 84 detects the collision of the vehicle V with the pedestrian M, the surrounding interfering object IV may interfere with the airbag 40 as the receiving member. If it is detected that the airbag 40 exists at a certain distance, that is, the allowable feeding space of the airbag 40 is small (restricted), the feeding length of the stopper material 60 is set to a short length dimension LS. (See the solid line in FIG. 4), the retractor 71 is controlled, and the interfering object IV is not present at a distance where there is a risk of interfering with the airbag 40 as a receiving member, that is, the feeding of the airbag 40. When it is detected that the allowable space is large (not limited), the retractor 71 is controlled so that the feeding length of the stopper member 60 has a long length dimension LL (see the two-point chain line in FIG. 4).

In the pedestrian protection device S1 of the first embodiment, when a collision with the pedestrian M occurs while the vehicle V is traveling, the control device 80 that has input a signal from the sensor 82 that detects the collision The inflator 42 is operated to inflate the airbag 40 that is also used as the actuator 30 and the receiving member. Then, pushed by the airbag 40 as the expanding actuator 30, the cover material 20 composed of the outer panel 3 as the vehicle body side member rotates with the hinge 4 on the lower end 22 side as the center of rotation and the upper end 21 side to the outside O of the vehicle. The vehicle V is moved from the standby position C0 on the side VS side to the feeding position C1 side, and is stopped at the feeding position C1 by the stopper material 60. At that time, the airbag 40 itself as a receiving member is also extended from the storage position P0 on the side VS side of the vehicle V to the receiving standby position P1 so that the pedestrian M can be received, and the road surface R and the pedestrian M can be received. Further, a cover material 20 is arranged on the road surface R side of the extended airbag 40 so as to prevent contact with the road surface R of the airbag 40 before receiving a pedestrian. Will be set up. Therefore, the airbag 40 as a receiving member before receiving the pedestrian M is prevented from coming into contact with the road surface R, so that the pedestrian M falls smoothly without being damaged by the road surface R. It can be received and protected.

In the first embodiment, the control device 80 that operates the inflator 42 also inputs a signal from the sensor 84 that detects the presence or absence of an interfering object IV in the vicinity, and the interfering material IV exists in the vicinity and receives the signal. If the allowable feeding space of the airbag 40 as a stop member is limited, the operation of the length adjusting mechanism 70 is controlled, the feeding length of the stopper material 60 is set to a short length dimension LS, and the cover material 20 is fed. The placement position of position C1 is regulated (see the solid line in FIG. 4). On the contrary, if the interfering object IV does not exist in the vicinity, the allowable feeding space of the airbag 40 as the receiving member is not limited. Therefore, the operation of the length adjusting mechanism 70 is controlled to feed the stopper member 60. The opening angle of the cover material 20 is increased so that the cover material 20 is arranged at the extension position C2 in which the upper end 21 of the cover material 20 is arranged on the outside O of the vehicle from the extension position C1. (See the alternate long and short dash line in FIG. 4). At that time, since the airbag 40 at the completion of expansion is supported on the upper surface (inner side surface) 23 side of the cover material 20, the airbag 40 is fed out from the receiving standby position P1 supported by the cover material 20 at the feeding position C1. The tip 40a is extended to the outside O of the vehicle up to the receiving standby position P2 supported by the cover material 20 at the position C2, and at that time, the cover is also between the airbag 40 and the road surface R. Since the material 20 is interposed, the airbag 40 can prevent damage due to contact with the road surface R before receiving a pedestrian.

Therefore, in the pedestrian protection device S1 of the first embodiment, the airbag 40 as a receiving member that receives and protects the pedestrian M comes into contact with the road surface R before receiving the pedestrian M by the cover material 20. It is possible to prevent damage caused by pedestrian M, and to receive and protect the pedestrian M smoothly during operation.

Then, in the pedestrian protection device S1 of the first embodiment, the receiving member is an airbag 40 that allows the expansion gas to flow in and is supported on the upper surface 23 side of the cover material 20 arranged at the feeding position C1. It has good cushioning and can catch pedestrian M. When the receiving member is composed of the airbag 40, the outer surface 40c side is not directly supported by the upper surface 23 side of the cover material 20 because it can exhibit a certain degree of shape retention when the expansion is completed. That is, even on the side of the tip 40a protruding from the upper end 21 of the cover material 20, the pedestrian M can be received and protected, and the airbag 40 walks as an area wider than the cover material 20 arranged at the feeding positions C1 and C2. Person M can be received and protected.

Further, in the first embodiment, the airbag 40 constituting the receiving member is covered with the cover material 20 at the standby position C0 and stored, and when the expansion gas flows in, the cover material 20 is fed out from the standby position C0. It is also used as an actuator 30 for moving to positions C1 and C2. Therefore, in the first embodiment, it is not necessary to separately prepare an actuator for moving the cover material 20, and the number of component parts can be reduced. Of course, an actuator for moving the cover material 20 may be prepared separately from the airbag 40.

Further, in the first embodiment, the stopper material 60 is connected to the retractor 71 as the length adjusting mechanism 70 so that the length dimension for feeding out the cover material 20 can be changed to a long length dimension LL or a short length dimension LS. Therefore, the length adjusting mechanism 70 is configured to adjust the length dimension of the stopper member 60 according to the presence or absence of the allowable feeding space of the airbag 40 as a receiving member at the time of feeding.

Therefore, in the first embodiment, when there is an interfering material IV on the side of the vehicle V and the allowable feeding space of the airbag 40 as a receiving member is limited, the presence of the interfering material IV is present. The retractor 71 of the length adjusting mechanism 70 is adjusted by the control of the control device 80 based on the signal from the sensor 84 to detect, and the cover material 20 is provided with the stopper material 60 adjusted to a predetermined short length dimension LS. It is fed to the feeding position C1 in which the opening is made small and the feeding space is made small (see the solid line in FIG. 4). Therefore, the airbag 40 as a receiving member that is delivered during operation can reduce the feeding space by the cover material 20 having a small opening, and can avoid the interference of the pedestrian M with the interfering object IV before receiving. It is possible to prevent damage due to contact with the interfering material IV and smoothly receive and protect the pedestrian M after the primary collision in a state where the expansion is completed.

Of course, if there is no interfering substance IV around the vehicle V and the allowable feeding space of the airbag 40 as a receiving member is not limited, a signal from the sensor 84 that detects the absence of the interfering substance IV is detected. The retractor 71 of the length adjusting mechanism 70 is adjusted by the control of the control device 80 based on the above, and the cover material 20 is widened by the stopper material 60 adjusted to a predetermined long length dimension LL, and the feeding space is widened. Is extended to the extension position C2 in which is increased. Therefore, the airbag 40 as a receiving member that is delivered during operation can also avoid contact with the road surface R before the pedestrian M is received by the cover material 20, and can prevent damage due to contact with the road surface R. As a result, the feeding space can be increased and expanded, and the pedestrian M after the primary collision can be smoothly received and protected.

In the first embodiment, the airbag 40 is used as the receiving member for receiving the pedestrian M, but the receiving member can be used as in the pedestrian protection device S2 of the second embodiment shown in FIGS. 5 to 8. It may be composed of a net 45 having flexibility. The net 45 is formed by knitting a string made of twisted threads made of synthetic resin or the like into a mesh shape or a lattice shape so that the pedestrian M can be received with good cushioning properties, and the cover material 25 at the feeding positions C1 and C2. It is arranged so as to be suspended near the upper end 26 of the vehicle V and the side surface VS side of the vehicle V. Specifically, the tip 46 side of the net 45 is connected to the upper end 26 side of the cover material 25, and the base 47 side is the side VS side of the vehicle V near the upper end 26 of the cover material 25 at the standby position C0. Is connected to the portion 9a of the inner panel 9 of the side member 6 as a vehicle body side member.

The cover material 25 of the second embodiment is composed of an outer panel 7 in an inverted U-shaped side member 6 that surrounds the two doors 2 (F, B) of the vehicle V. The lower end 27 side of the cover material 25 is supported by a hinge 8 arranged on the inner panel 9 of the side member 6 to serve as a rotation center at the time of feeding, and the upper end 26 side is rotationally moved to the outside O of the vehicle to stand by. It is operated so as to extend from the position C0 to the extension positions C1 and C2. If the net 45 is arranged at the feeding positions C1 and C2, the net 45 as a receiving member connects the tip 46 side to the upper end 26 of the cover material 25 at the feeding positions C1 and C2, and connects the base 47 side to the standby position C0. Since it is connected to the upper end 9a of the inner panel 9 near the upper end 26 of the cover material 25, the vicinity of the upper end 9a of the inner panel 9 and the vicinity of the upper end 26 of the open cover material 25 (the upper end 7a of the outer panel 7). It will be arranged so as to close the space. Of course, at this time, since the cover material 25 is arranged below the net 45, contact of the net 45 with the road surface R is prevented.

Similar to the first embodiment, the stopper material 62 for stopping the cover material 25 at the feeding positions C1 and C2 is formed of a flexible string material, and two of them are used, and the tip 62a side of each is used. , The front portion 26a and the rear portion 26b on the upper end 26 side of the cover material 25 are connected to each other. Further, each of these stopper members 62 has a base portion 62b connected to a retractor 76 as a length adjusting mechanism 75.

Each retractor 76 is arranged on the roof panel 11 side of the vehicle V, its operation is controlled by the control device 80 that inputs signals from the sensors 82 and 84, and the stoppers are controlled according to the arrangement of the surrounding interfering objects IV. The feeding length dimension of the material 62 is adjusted in two stages (LL, LS) of long and short.

Further, in the case of the second embodiment, the actuator 32 for feeding out the cover material 25 is provided as a cylinder type on the inner panel 9 side of the front portion 27a and the rear portion 27b above the hinge 8 on the lower end 27 side of the cover material 25. , It is fixed, and a gas generator is built in, and when it operates, it operates so as to extend the rod 33 to the outside O of the vehicle. If the rod 33 is extended when the actuator 32 is operated, the cover material 25 is pushed by the tip 33a of the rod 33 near the upper side of the hinge 8 to the outside O of the vehicle, and the upper end is centered on the hinge 8 on the lower end 27 side. The 26 side rotates to the outside O of the vehicle and moves from the standby position C0 to the feeding positions C1 and C2 according to the feeding length of the stopper member 62. The actuator 32 of the second embodiment has a short stroke for moving the rod 33 during operation so as to separate the cover material 25 from the standby position C0, and has a length for moving the cover material 25 to the feeding position C1. Instead, the cover material 25 pushed by the rod 33 is configured to move to the feeding positions C1 and C2 by the inertial force.

Also in this second embodiment, when a collision with the pedestrian M occurs while the vehicle V is traveling, the control device 80 that has input the signal from the sensor 82 that detects the collision operates the actuator 32. Therefore, the cover material 25 is pushed by the tip 33a of the rod 33 of the actuator 32, rotates around the hinge 8 on the lower end 27 side as the center of rotation, and rotates on the upper end 26 side to the outside O of the vehicle, and is predetermined from the standby position C0. The stopper member 62 that has been fed to the length moves to the feeding positions C1 and C2 according to the feeding length dimensions LS and LL. Then, when the cover material 25 moves, the net 45 as a receiving member moves to a receiving standby position P1 corresponding to the feeding position C1 of the covering material 25 and a receiving waiting position corresponding to the feeding position C2 of the cover material 25. As P2, the cover material 25 is suspended so as to close between the vicinity of the upper end 26 of the cover material 25 and the side VS side of the vehicle V, and a flexible space is provided on the lower side of the cover material 25 so as to have cushioning properties. , Will be placed. Therefore, the net 45 as a receiving member can receive and protect the pedestrian M falling to the road surface R side after the primary collision with good cushioning property.

Then, in the pedestrian protection device S2 of the second embodiment, when the cover material 25 is operated, the pedestrian M can be received by simply rotating the cover material 25, and the receiving member made of the net 45 is deployed from the stored state. be able to. Therefore, the pedestrian protection device S2 can be configured more easily than the case where the receiving member for which it is necessary to prepare the inflator (gas supply machine) 42 or the like for supplying the expansion gas is composed of the airbag 40.

Also in this second embodiment, the control device 80 that operates the actuator 32 also inputs a signal from the sensor 84 that detects the presence or absence of the surrounding interfering object IV, and the interfering material IV exists in the vicinity. If the allowable feeding space of the cover material 25 is limited, the operation of the length adjusting mechanism 75 is controlled so that the feeding length of the stopper material 62 is set to the short length dimension LS, and the feeding position C1 of the covering material 25 is arranged. The position is regulated (see the solid line in FIG. 8). On the contrary, if the interfering object IV does not exist in the vicinity, the allowable feeding space of the cover material 25 is not limited. Therefore, the operation of the length adjusting mechanism 75 is controlled to increase the feeding length of the stopper material 62. As the dimension LL, the opening angle of the cover material 25 is increased, and the cover material 25 is adjusted to be arranged at the extension position C2 in which the upper end 26 of the cover material 25 is arranged on the outside O of the vehicle from the extension position C1 (FIG. See the alternate long and short dash line in 8). At that time, since the net 45 as a receiving member can be extended in a mesh shape so that the pedestrian M at the time of receiving does not come into contact with the road surface R, the net 45 is located outside the vehicle O from the receiving standby position P1. Even if the tip 46 is arranged at the receiving standby position P2, the tip 46 is suspended so as to close between the vicinity of the upper end 26 of the cover material 25 at the feeding position C2 and the side VS side of the vehicle V, and the lower side. Since the space is provided so as to have cushioning properties, the pedestrian M falling to the road surface R side after the primary collision can be received and protected with good cushioning properties.

When a net is used as the receiving member, it may be configured like the pedestrian protection device S3 of the third embodiment shown in FIGS. 9 to 11.

In the pedestrian protection device S3 of the third embodiment, the cover material 25A is composed of the outer panel 7 on the side members 6 around the door 2 (F, B), similarly to the cover material 25 of the second embodiment. It is arranged in an inverted U shape on the side VS side of the vehicle V. Similar to the second embodiment, the cover material 25A is stopped by the stopper material 62 from the standby position C0 by the operation of the actuator 32 with the hinge 8 provided on the inner panel 9 on the lower end 27 side as the center of rotation. The upper end 26 side rotates and moves to the outside O of the vehicle up to the feeding positions C1 and C2.
