A seat belt buckle (10, 50) has a first end (56) configured for fixing the seat belt buckle (10, 50) to a component of a vehicle and a second end (58) opposite the first end provided with a seat belt buckle tongue ejection button (28, 60) and a slot (26) for receiving a seat belt buckle tongue (10a), the seat belt buckle includes at least one clear polycarbonate light diffuser (34, 64, 66) and a light source (39, 40, 41) for providing light to be transmitted through the light pipe.

A restraint system includes a first member including a first hole and fixable to a seat frame, a second member including a second hole and slidably coupled to the first member between a retracted position in which the first and second holes are aligned and an extended position in which the first and second holes are spaced from each other, a buckle housing fixed to the second member, and a tongue including a third hole and insertable into the buckle housing to an inserted position in which the second and third holes are aligned.

A buckle for a seat belt device has a latch member that is configured to be engaged with a tongue when the tongue is inserted into the buckle; a buckle base having a bottom wall and a first side wall and a second side wall that stand up from the opposite side edges of the bottom wall, each of the first and second side walls having latch holding portions that hold the latch member, the latch holding portions each being formed of a cutout extending from an upper end of each of the first and second side walls of the buckle base; and a bridging member configured to be assemblable to the first and second side walls so as to span the latch holding portions in a front-rear direction.

A seat belt buckle (10, 50) has a first end (56) configured for fixing the seat belt buckle (10, 50) to a component of a vehicle and a second end (58) opposite the first end provided with a seat belt buckle tongue ejection button (28, 60) and a slot (26) for receiving a seat belt buckle tongue (10a), the seat belt buckle includes at least one clear polycarbonate light diffuser (34, 64, 66) and a light source (39, 40, 41) for providing light to be transmitted through the light pipe.

At a present buckle device, lateral slits are formed in lateral portions of a slider of a buckle switch. A tab is formed at a portion, which is further toward a device upper side than the lateral slit, of a lateral portion that is at a device left side. A portion, which is further toward a device lower side than the lateral slit, at the lateral portion is an elastic portion, and a magnet is held thereat. Therefore, even if the tab receives pushing force from an ejector and is deformed, deformation arising at the elastic portion can be suppressed, and holding of the magnet can be stabilized.

A belt buckle for a seat belt system having a support member (12) including a belt buckle mechanism, first and second shells (16, 18) which together encompass the support member (12) and an annular cover member (14) surrounding an end face of the support member (12). Along the periphery of the annular cover member (14) at feast a first structure (24) is formed and in the area of a rim (28) of the first and second shells (16, 18) directed to the annular cover member (14) a respective second structure (26) is formed. The first and second structures (24, 26) are engaged with each other and fix the first and second shells (16, 18) to the annular cover member (14).

A belt buckle for a vehicle safety belt, comprising a housing (3) which is formed by at least two housing shells (1,2) joined together and in which a locking mechanism (4) is arranged, and a pushbutton (22), provided on said housing, for operating the locking mechanism (4), wherein at least two housing shells (1,2) are joined together at their shell rims and that elongated cover strips (8,9) made of solid material and covering the mutually abutting rims (17,18) of the housing shells (1,2) are fixed to the joined housing shells (1,2).

A safety buckle device includes a first buckle part having a partially closed space with an opening, and a second buckle part having a body, a guiding tongue, and a control key. When locking the safety buckle device, a springing detent is adapted to lock against a locking element. The control key has two recesses having different depths and arranged adjacent each other in the longitudinal direction of the control key. The detent achieves a first locking when the control key is actuated, and the detent achieves a second locking when the control key no longer is actuated, or the detent achieves a locking when the control key is not actuated. The detent is adapted to be released when the control key is actuated again, or when the control key is actuated.

A buckle for a connector having a small simple structure and a favorable productivity, and a method for assembling the same. A buckle for connector of the present invention for supporting a tongue engageably/disengageably includes a base member, a latch member, an unlocking member, a latch spring, an ejector, an ejector spring, and cover members housing these members. The base member includes first and second plates. The ejector includes: two arms; a body section between the arms that includes a pushing/moving surface for the tongue to be pushed/moved by the tongue, a support section to support the latch member, and a pushing surface to be pushed by the ejector spring; and claws formed at ends of the arms and locked with an aperture at a terminal end of the base member, the terminal end being opposite to a starting end from which the tongue is inserted.
