| 发明名称 | Belt buckle with release lock | ||
| 摘要 | A belt buckle (10) for a seat belt includes a buckle housing (16), a locking mechanism for locking a plug-in tongue inserted in the buckle housing (16), a release button (22) which is movable in a first direction relative to the buckle housing (16) for unlocking the plug-in tongue, and a safety mechanism for preventing automatic displacement of the release button (22) in the first direction. The safety mechanism includes a mass body (36) movable in the first direction relative to the buckle housing (16) and a movably supported coupling lever (24) including an axis of rotation which is stationary relative to the buckle housing (16). The coupling lever (24) is coupled to the mass body (36) and to the release button (22) so that, upon acceleration of the belt buckle (10) in a second direction opposed to the first direction, it transmits an inertia force acting on the mass body (36) in the first direction to the release button (22) in the opposite second direction. | ||

| 主权项 | 1. A belt buckle (10) for a seat belt comprising a buckle housing (16), a locking mechanism for locking a plug-in tongue inserted in the buckle housing (16), a release button (22) which is movable in a first direction A relative to the buckle housing (16) for unlocking the plug-in tongue, and a safety mechanism for preventing automatic displacement of the release button (22) in the first direction A, wherein the safety mechanism includes a mass body (36) movable in the first direction A relative to the buckle housing (16) and a rotatably supported coupling lever (24) having an axis of rotation C which is stationary relative to the buckle housing (16), and wherein the coupling lever (24) is coupled to the mass body (36) and to the release button (22) so that upon acceleration of the belt buckle (10) in a second direction B opposed to the first direction A it transmits an inertia force acting on the mass body (36) in the first direction A to the release button (22) in the opposite second direction B, wherein a latch mechanism which, upon acceleration of the belt buckle (10) in the first direction A, delimits a displacement of the mass body (36) in the second direction B due to the inertia force acting on the mass body (36) in the second direction B. | ||
