摘要： In a buckle for a seat belt, lower ends of side walls of an operational button is positioned at a level lower than lower ends of guide portions of a base, and an upper surface of a portion of a lower cover defining a tongue-insertion opening is positioned at a level higher than an upper surface of a bottom of the base. Therefore, when a tongue is engaged with the buckle, an engaging portion of the tongue touches at least one of the side walls of the operational button made of resin, and the portion of the lower cover made of resin. Thus, the tongue is prevented from touching the guide portions and the bottom of the base made of metal, thereby preventing a noise due to the metal-to-metal contact when the tongue 3 is inserted into the buckle and engaged with the buckle. Therefore, a jar on an occupant's nerve when wearing the seat belt can be avoided.
摘要翻译：在用于安全带的扣环中，操作按钮的侧壁的下端位于比底座的引导部的下端低的水平面上，并且下盖的限定舌插入口的部分的上表面位于比基座的底部的上表面高的水平。因此，当舌头与带扣接合时，舌头的接合部分接触由树脂制成的操作按钮的至少一个侧壁，并且下盖的部分由树脂制成。因此，防止舌头接触由金属制成的底座的引导部分和底部，从而防止当舌片3插入带扣并与扣环接合时由于金属对金属接触的噪音。因此，能够避免佩带安全带时乘坐者的神经的罐子。

摘要： A buckle is formed of a base having two side walls, a cover for accommodating and supporting the base, and having a tongue insertion hole formed at one end side of the two side walls of the base, and guide portions provided on each of the two side walls to protrude inwardly therefrom for leading a tongue to be inserted through the tongue insertion hole. The guide portions lead a tip of the tongue smoothly without blocking even when the tongue is inserted from the tongue insertion hole at a maximum slant posture defined by the tongue insertion hole relative to the buckle. The tongue can be smoothly inserted into the buckle to improve the manipulation feeling in inserting the tongue.
摘要翻译：扣具由具有两个侧壁的底座，用于容纳和支撑基座的盖子形成，并且在基座的两个侧壁的一个端侧形成有舌插入孔，并且在两个侧壁中的每一个上设置有引导部侧壁从其向内突出，用于引导舌片通过舌插入孔插入。即使当舌片以舌插入孔相对于带扣限定的最大倾斜姿势从舌插入孔插入时，引导部分也能平滑地引导舌头的尖端。舌头可以顺利地插入到带扣中以改善插入舌头的操作感觉。

摘要： A buckle is provided with a non-contact buckle switch improved in durability to be securely operated. The non-contact buckle switch is switched by detecting a movement of one of an ejector, latch member and lock member of the buckle. The buckle switch includes a magnet and a Hall element for generating an electromotive force by a magnetic field of the magnet. One of the magnet and the Hall element is attached to a fixed member, and the other of the magnet and the Hall element is attached to one of the ejector, latch member and lock member.

摘要： In a latched state of a buckle in which a tongue is engaged, an inertia lever member of a movement preventing device enters into a path of a lock pin. When the buckle is pulled by a buckle pretensioner in this state, the inertia lever member moves in the longitudinal direction, and pressed portions of the inertia lever member are held by a holding portion, so that the inertia lever member does not pivot and the levers are thus held in the path of the lock pin. At the end of pretensioning, the buckle is stopped. Since the moment produced by the inertia force acting on the center of gravity of mass body of the movement preventing device is larger than the moment produced by the inertia force of an operational button, the inertia lever member does not pivot, so that the inertia lever member can be held in the path of the lock pin. In the buckle, the inertia release can be effectively prevented with a simple structure.
摘要翻译：在其中接合舌片的带扣的闩锁状态下，防止移动装置的惯性杠杆构件进入锁定销的路径。当在这种状态下由带扣预紧器拉动带扣时，惯性杆构件沿长度方向移动，并且惯性杆构件的按压部分被保持部分保持，使得惯性杆构件不枢转，并且杆因此被保持在锁定销的路径中。预拉伸结束时，扣环停止。由于作用于防止移动装置的质量体的重心的惯性力产生的力矩大于由操作按钮的惯性力产生的力矩，因此惯性杆构件不枢转，因此惯性杆会员可以锁在锁销的路径上。在扣环中，可以通过简单的结构有效地防止惯性释放。

摘要： A shock-proof device disposed in a buckle includes at least a latch member for engaging a tongue so as to latch the tongue; a release button for releasing the tongue from the latch member; and an inertia lever with a rotation shaft rotatably arranged for preventing the release button from moving at least in a release direction of the release button by abutting against the release button. The shock-proof device further includes torque-difference generating mechanism for generating a torque difference between a first torque and a second torque. The first torque is applied to the inertia lever when the inertial force is applied to the release button and the inertia lever in the release direction of the release button. The second torque is applied to the inertia lever when the inertial force is applied to the release button and the inertia lever in the non-release direction of the release button.

摘要： A buckle that is compact in a longitudinal direction and uses an unlatching force that may be effectively applied to a latch member when releasing a tongue from a buckle. The buckle is configured so that as an operation button is manipulated in the unlatching direction from a state in which a tongue and a latching portion of a latch member are latched, the slider moves so that the inclined face of a pressed portion of the slider comes in contact with the inclined face of a pressing portion of an ejector and presses the ejector. Then, the ejector is spaced from the tongue and the biasing force of an ejector spring is effectively applied to the latch member via the ejector and the slider in the unlatching direction. An unlatching force is thereby applied to the latch member so that the latch member pivots in the unlatching direction, causing release of the tongue.
