Abstract: PROBLEM TO BE SOLVED: To provide an active knee bolster which is lightweight and capable of enhancing the absorbing performance of the collision energy. SOLUTION: An actuator 32 of the active knee bolster 24 has a double structure consisting of an inner cylinder 48 with a lower limb constraint unit 30 supported thereby and an outer cylinder 46 which is fixed to an instrument panel reinforcement 33 of a vehicle body, and movably supports the inner cylinder 48 with an inflator 60 connected thereto. A plurality of balls 64 to stop the movement of the inner cylinder 48 by the gradual deformation of the outer cylinder 46 when the inner cylinder 48 is subjected to the load over the predetermined value forward of the vehicle body are arranged between an inclined portion 48D of the inner cylinder 48 and the outer cylinder 46.

Abstract: PROBLEM TO BE SOLVED: To regulate the operating position of a lower limb constraining section by adjusting to the physique of a passenger, and at the same time, to make the miniaturization of the lower limb constraining section and the facilitation of the control possible. SOLUTION: On the rotating track of a first arm 42 which moves the lower limb constraining section 30 of an active knee bolster 24 to a lower limb constraining position, a stopper pin 62 which changes the moving position of the lower limb constraining section 30 in a manner to be able to go out/come in freely is arranged. A control circuit 14 judges whether a passenger 28 has a large physique or a small physique based on load data from a load sensor 68 which is provided on a front seat 20. When the passenger 28 is judged to have the small physique, a moving position changing actuator 64 is operated, and the stopper pin 62 is moved onto the rotating track of the first arm 42.

Abstract: In a knee protection system according to the present invention, a knee protection panel is driven from a standby position surrounded by an interior member to the vehicle rear side to a knee-protecting position in front of the knees of an occupant by a drive mechanism when the vehicle is crashing, whereby the knees moving forward are protected by the knee protection panel thus driven. The drive mechanism includes a holding portion for holding the knee protection panel in such a manner that the knee protection panel is moved rearward. Engagement portions are provided, respectively, at locations where the holding portion and the knee protection panel connect with each other in such a manner as to be brought into engagement with each other. These engagement portions are brought into engagement with each other when the holding portion is moved rearward due to the activation of the drive mechanism in such a manner as to prevent displacement of the knee protection panel relative to the holding portion while moving the knee protection panel rearward, as well as allowing the knee protection panel to be displaced vertically and horizontally relative to the holding portion prior to the activation of the drive mechanism. With the knee protection system according to the invention, the knee protection panel can be disposed at the standby position so as to have a visually attractive break with the surrounding interior member, without deteriorating mounting work efficiency.

Abstract: An actuator (32) of an active knee bolster (24) is provided with a drive force generation device (38) and a one way lock mechanism (40) that is disposed in the vicinity of an operation end of the drive force generation device (38). The one way lock mechanism (40) is configured such that, if attempted movement of a piston member (42) in an inward insertion direction occurs, respective engagement portions (64) are moved to a taper portion (62B) by urging force of a spring (66), whereby the engagement portions (64) are abutted against an external periphery surface of the piston member (42) such that the piston member (42) and the engagement portions (64) are fixed. Accordingly, as a result of the one way lock mechanism (40), a main body (30) of the active knee bolster (24) that has been moved to a restraining position cannot return in a vehicle forward direction, and thus it is possible to generate a substantial restraining force that restrains a lower limb (28A) of an occupant (28).

Abstract: PROBLEM TO BE SOLVED: To provide an active knee bolster capable of reducing the cost and weight. SOLUTION: When the lower limb restricting part 30 of a right active knee bolster 24A moves, the lower limb restricting part 30 of a left active knee bolster 24B connected to it through a connecting panel 34 moves. At this time, the rigidity of the connecting panel 34 is low and the left end 34B of the connecting panel 34 tilts front side (arrow B direction) of the vehicle body. However, a lock 64 for passing a rod 70 of the left active knee bolster 24B is rotated in the tilting direction (arrow C direction) of the connecting panel 34 with respect to a bracket 38 by a screw 66 with a step.

Abstract: PROBLEM TO BE SOLVED: To provide a riding person protection device for vehicle capable of improving convenience in a car interior. SOLUTION: When an actuator 32 of an active knee bolster 26 works, a main body 30 of the active knee bolster 26 rotates and moves along a design surface 18A on an instrument panel 18 to the side of a lower leg 28A of a riding person 28 (arrow A direction) from a storage position and moves to a position to constrain the lower leg 28A of the occupant 28. That is, the main body 30 of the active knee bolster 26 is stored below a globe box 24 in the case when the active knee bolster 26 does not work. Consequently, it is possible to arrange the globe box 24 at a position easy to use it on the installment panel 18 and to improve the convenience in the car room. COPYRIGHT: (C)2004,JPO&NCIPI
