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

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle seat capable of enlarging the vertical strokes of a load receiving member such as a plane spring in a seat with a displacement sensor. SOLUTION: In this vehicle seat, the plane spring 15 as a load receiving member is provided in a seat frame 14, and it is configured to be supported through supporting springs 32a-32f provided between the seat frame 14 and itself. In the seat frame 14, displacement sensors 20a-20d with a pulley 34 are provided. The rotation center of the pulley 34 is positioned lower than the plane spring 15. A wire rope 35 is wound around the pulley 34 as a pulling member, and it is pulled out from the bottom side of the pulley 34 obliquely upward and connected to the plane spring 15. The plane spring 15 moves downward as a load from above increases, and at that time the pulley 34 is rotated in the winding direction of the wire rope 35. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a knee protecting device enabling a shock absorbing member to effectively absorbing shock. SOLUTION: A frame 36 fixed on a moving frame 30 supports a restraining member 48 and the moving frame 30 and the frame 36 are moved rearward to arrange the restraining member 48 just in front of knees of an occupant in collision of a vehicle in an active knee bolster 10. Consequently, the frame 36 is deformed by receiving impact on the restraining member 48 from the knees of the occupant and the shock is absorbed. A lateral extension part 38 is extended to a right side or a left side and the longitudinal extension part 42 is extended upward from a tip of the lateral extension part 38 in the frame 36. Consequently, the frame 36 is not only mainly elastically deformed at the longitudinal extension part 42 to absorb the shock but also torsionally deformed at the lateral extension part 38 to absorb the shock. Consequently, the frame 36 can effectively absorb the shock. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a knee protector capable of securing a protection area to be large and exactly protecting the knee of a driver. SOLUTION: The knee protector S is arranged under a steering column 6 on the front side of the knee K of the sitting driver MD, a restraining body 44 connected with a driving mechanism 52 is moved to the back side of the vehicle in operating the driving mechanism 52, and the knee K is protected by the surface on the vehicle back side of the restraining body 44. The steering column 6 has a column body 7 and a column cover 10 arranged so as to cover the periphery of the column body 7. The column cover 10 has a downside cover section 15 for covering the driver MD side on the downside of the column body 7. The lower end proximity of the downside cover section 15 is connected with the proximity of the upper end of the restraining body 44, and the downside cover section 15 can be moved to the back side of the vehicle together with the restraining body 44 in operating the driving mechanism 52. The downside cover section 15 can protect the knee K with the surface on the back side of the vehicle after the movement. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To allow an occupant to easily get out a vehicle after completion of a lower limb restricting operation. SOLUTION: When an active knee bolster 20 operates and a body 22 of the active knee bolster 20 rotates toward the back of the vehicle about a shaft 44, a wire 48 connected to a bracket 40 of the active knee bolster 20 moves, and a shaft member 58 of a footrest 50 connected to the other end section 48B of the wire 48 moves toward the back of the vehicle along a slit 56 of the base 54 of the footrest 50. Thus, a footrest supporting bracket 60 rotates toward the front side of the vehicle about the shaft member 58, the body 66 of the footrest 50 falls toward the front side of the vehicle about a shaft member 70, thereby decreasing tilting angle θ1 of the body 66 with respect to the floor 52.
