| 本发明提供一种安全带卷收器及具有该安全带卷收器的安全带装置，以进一步简化能量吸收销的装配作业并能获得稳定的限制载荷，提高生产率。能量吸收销(19)的头部(19b)中的扣合面(19b1)为圆弧状弯曲面。在能量吸收销(19)的装配状态下，扣合面(19b1)与锁定基座(16)的凹部(16a)的底部(16a1)抵接。如果卷轴(9)相对于锁定基座(16)沿安全带拉出方向相对旋转，则由锁定基座(16)向头部(19b)施加锁定基座(16)旋转方向的弯曲力。此时，由于扣合面(19b1)为圆弧状弯曲面，因此，头部(19b)容易旋转，能量吸收销(19)在拔出初期限制载荷不会急剧增大，因而能够抑制EA工作初期时限制载荷的过冲。 | ||||||

| PROBLEM TO BE SOLVED: To provide a webbing take-up device having a force limiter capable of enhancing initial restraining performance. SOLUTION: Shear ribs 76, 82 are formed on the bottom part 72A of the engagement hole 72 of a spool 20 for positioning a lock base 40, the end part 74A of a positioning part 74 abuts on the shear rib 76, and the end part 74B of the positioning part 74 abuts on the shear rib 82. Ribs 78, 80 are formed between the shear ribs 76, 82. If the spool 20 rotates in the withdrawal direction with respect to the lock base 40, the end part 74A of the positioning part 74 deforms and ruptures the shear rib 76, the shear ribs 78, 80, and the shear rib 82 in this order, an amount of absorbed energy for this deformation part of each rib 76-80 is superimposed on the torsional deformation part of a torsion bar, and thereby, a force limiter load right after the rotation start of the spool 20 is increased. | ||||||

| A seat belt retractor for a vehicle seat belt has a belt reel for the seat belt. A free-flowing load limiting medium is arranged in a working chamber. A displacement means is drivable by the belt reel. The load limiting medium is transported through at least one flow channel by the displacement means. The flow cross-section in the flow channel is selected as a function of the kinematic viscosity of the load limiting medium, to achieve a belt force limitation profile over time which approaches that of a torque rod. | ||||||

| A safety belt apparatus for motor vehicles comprising a safety belt and a deflecting device for the safety belt which is connected to a holder which can be fastened to the vehicle via an absorption unit. The deflecting device being movable in an absorption direction by forces occurring relative to the holder with a pulling movement of the safety belt caused by an accident while overcoming an opposing absorption resistance of the absorption unit. The deflecting device being hindered from making a movement in the absorption direction with forces occurring in normal operation. The absorption unit being changeable in shape by the deflecting device moving in the absorption direction in order to overcome the absorption resistance. | ||||||

| Shear ribs are formed at a bottom portion of a fitting hole of a spool for positioning a lock base, and respective end portions of the positioning portion abuts on a shear rib. Further, ribs are formed between the shear ribs. When the spool rotates in an unwinding direction with respect to the lock base, the end portion of the positioning portion deforms and breaks a shear rib, a rib and then another shear rib in that order. By being able to combine the effects of energy absorption due to deformation of the ribs with that of energy absorption due to twisting deformation of the torsion bar, a force limiter load immediately increases as soon as the spool starts to rotate. | ||||||

| In a seat belt retractor, as the rotation of a pawl holder of a locking member in the webbing unwinding direction is stopped by a locking mechanism in emergency, a reel receives a force on a protrusion by impact load applied to the webbing with the inertia of an occupant. As the force is increased, the protrusion is plastically deformed. By this plastic deformation, the impact on the occupant can be greatly absorbed at first. After the protrusion is sheared, the reel tends to rotate in the webbing unwinding direction by the inertia of the occupant, so that the torsion bar is further twisted. Thus, the load can be variously set to effectively absorb kinetic energy of the occupant. | ||||||

| A seat belt system for a vehicle including an impact energy absorbing device mounted between a seat belt for restraining an occupant and a seat belt anchor means. The impact energy absorbing device includes a cutter, a member disposed in juxtaposed relation to the cutter and adapted to be sheared by the cutter as the member and the cutter move relative to each other, and a cutter supporting member to which the cutter is securely fixed. When the vehicle collides, the impact energy is absorbed by the shearing of the member by the cutter. The shearing load exerted on the member may vary depending on the tension speed exerted on the seat belt at the time of collision, so that the movement of the occupant caused by the collision can be confined to a substantially constant range at varying collision velocities and a secondary collision of the occupant against an instrument panel or the like can be prevented. | ||||||
