Abstract
Description
[0001] Standard car seat belt buckle lock
[0002] Field of technology
[0003] The utility model relates to the field of safety systems in cars and is used with standard car seat belts to safely restrain children.
[0004] State of the art
[0005] The closest analogue is a device that fits over the buckle of a standard car seat belt and prevents the release button from being pressed. To open the belt, you must first remove the device and then, after opening, reattach it to the buckle.
[0006] Disclosure of a utility model
[0007] The technical result of the claimed utility model is: - a single installation of the standard car seat belt buckle lock blocker onto the standard seat belt buckle bracket is required, rather than multiple installation-removal cycles;
[0008] - the standard car seat belt buckle lock allows you to easily fasten your seat belt yourself or be fastened with the standard car seat belt;
[0009] - the locking device for the buckle of the standard car seat belt makes it very difficult for a small child to unfasten the standard car seat belt independently or accidentally, since more force is required;
[0010] - The standard car seat belt buckle lock allows you to easily and intuitively unfasten the standard car seat belt, whether it is done by an adult or an adult child.
[0011] The specified technical result is achieved by a standard vehicle seat belt buckle lock blocker, consisting of a polyhedron made of an elastic material, in which a slot is made in the shape of the standard vehicle seat belt buckle bracket, which is placed on the standard vehicle seat belt buckle bracket and covers the standard vehicle seat belt buckle lock release button.
[0012] This way, a child won't be able to unfasten their seat belt while driving, but an adult can easily do so. Brief description of the drawings
[0013] Figure 1 shows a general view of the locking mechanism of the standard car seat belt buckle, at an angle
[0014] Figure 2 shows the bracket of the buckle of the standard car seat belt, at an angle
[0015] Figure 3 shows the fastening of the buckle lock blocker on the buckle bracket of the standard car belt, at an angle. Figure 4 shows the fastening of the buckle lock blocker on the buckle bracket of the standard car belt, assembled with the standard buckle lock, at an angle.
[0016] Figure 5 shows the fastening of the standard vehicle seat belt buckle lock blocker on the standard vehicle seat belt buckle bracket assembled with the standard buckle lock, at an angle, and the pressing force vector for accessing the standard buckle lock.
[0017] Implementation of a utility model
[0018] A standard vehicle seat belt buckle lock blocker consisting of a polyhedron made of elastic material with a slot in the shape of the standard vehicle seat belt buckle bracket, which is placed on the standard vehicle seat belt buckle bracket and covers the standard vehicle seat belt buckle lock release button.
[0019] The standard car seat belt buckle lock shown in the figures is used as follows.
[0020] Its purpose is to block the release button of the standard car seat belt buckle. To open the buckle, press the locking mechanism of the standard car seat belt buckle with a force too strong for a child to free access to the button (squeeze it laterally) and simultaneously press the release button of the buckle.
[0021] The device is designed to improve the safety of children while transporting them. Thus, the claimed utility model of the standard car seat belt buckle lock is characterized by a simple design, making it lighter, less expensive, and easier to use, while simultaneously improving child safety.
