摘要： PROBLEM TO BE SOLVED: To solve a problem wherein the protective function for an occupant in a rear seat is hardly degraded even when the positional relationship of a front seat to the occupant in the rear seat is changed. SOLUTION: In an airbag device for a rear seat, a controller 37 estimates a spacing between a back rest part of a front seat and knees of an occupant in the rear seat based on detected information by a front seat position sensor 32, a front seat collapse angle sensor 33 or the like. The controller 37 operates only a first inflator 15a when the estimated spacing is less than a predetermined value, and operates the first and second inflators 15a and 15b if the spacing is not less than the predetermined value. An airbag is developed and inflated thin by maintaining an overlapping part without breaking a tear seam part provided on an overlapping part of a tether when gas is supplied only from the first inflator 15a. The airbag is developed and inflated thick by breaking the tear seam part and developing the overlapping part when gas is supplied from the first and second inflators 15a and 15b.

摘要： PROBLEM TO BE SOLVED: To provide a shock absorbing body for a vehicle capable of suppressing a sharp load at a last stage in a F-S curve of the shock absorbing body for the vehicle with a shock absorbing part formed in a grid-shape or the like by connecting thin thickness ribs. SOLUTION: The shock absorbing body to be attached to a rear surface of a restraint panel or the like which protrudes toward an occupant side to protect occupant knee parts forms the plurality of thin thickness ribs 44 to intersect each other on a support plate 41, and absorbs shock energy by being plastically deformed when the shock load is applied. A taper cross section 44a and an inverse taper cross section 44b are provided in erected directional cross sections of the thin thickness ribs 44 so that generation of the sharp load at the last stage in a load (F)-displacement quantity (S) is suppressed. Both taper cross sections 44a, 44b utilize a tip end part side being a side to which a shock load is applied as reference. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To effectively protect knees and lower portions thereof, mainly foot tips of occupants seated in a rear seat. SOLUTION: In the airbag device for the rear seat, an airbag 16 which is developed and inflated between a front seat 11 and a rear seat 15 is stored in a case 13 of an airbag module 10 fixed to a lower side of a seat part 12 of the front seat 11. The airbag 16 comprises an upper inflation part 22 which is developed and inflated along a back rest part 21 of the front seat 11, a lower inflation part 23 to cover a space between the seat part 12 and a floor F. A support guide 24 to support a front face 23a of the lower inflation part 23 is provided on a lower side of the case 13 between the seat part 12 and the floor F. The lower inflation part 23 is brought into contact with the floor F. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a knee protective device capable of suppressing increase of weight or volume, absorbing kinetic energy of knees at the time of vehicle collision, and protecting knees. SOLUTION: The knee protective device S1 has a knee protective panel 21 drawn out to a front side of the knees K of an occupant M by a driving mechanism 30 at the time of the vehicle collision. The panel 21 has a panel main body 22, and shock absorbing material 25 positioned at a front face side of the panel main body 22, capable of being plastically deformed so as to absorb the kinetic energy. The driving mechanism 30 has a support plate 33 for supporting the shock absorbing material 25, and a driving source 31 for drawing out the support plate 33 to the front side of the knees K along with the panel 21 at the time of the vehicle collision. The shock absorbing material 25 gradually reduces a cross section in a vertical direction from a panel main body side to a support plate side by making projection area of fore-and-aft direction smaller than the panel main body 22. The support plate 33 is set to be almost the same shape as that of the front face side of the shock absorbing material 25 to support the shock absorbing material 25. COPYRIGHT: (C)2006,JPO&NCIPI
