Safety seat belts for vehicles

Claim 2

A safety seat belt assembly incorporating a two-part separable buckle of which the first part, to which lap and diagonal straps are adapted to be connected, has a readily releasable engagement with a second part which is adapted to be connected to a floor anchorage, the first part comprising a shank terminating in a tapered portion, a head of substantially the same cross-sectional dimensions as the shank at the end of the tapered portion providing a continuous circumferential shoulder facing in the direction of the shank, and the second part comprising a rigid sleeve having laterally extending parallel flanges, aligned openings in said flanges, an axial opening in said sleeve for receiving the shank, a latch member rockably mounted in said aligned openings and having a portion for engagement with said shoulder in the first part, said latch member extending from the engaging position within said sleeve to a position adjacent said axial opening, the portion adjacEnt the axial opening being outside of the sleeve for operating said latch member, and a spring biassing the latch member to the engaged position.

Claim 3

A safety seat belt assembly as in claim 1 wherein the headed shank is rotatable relative to the sleeve.

Claim 4

A safety seat belt assembly incorporating a two-part separable buckle of which the first part, to which lap and diagonal straps are adapted to be connected, has a readily releasable engagement with a second part which is adapted to be connected to a floor anchorage, the first part comprising a headed shank and a circumferential shoulder around said shank behind said head, and the second part comprising a rigid sleeve having laterally extending parallel flanges, said sleeve having an axial opening for receiving the shank, aligned sector-shaped opening in said flanges, an elongated latch member having an end portion adapted to engage the shoulder on said shank the latch member extending from said end portion in the direction of the axial sleeve opening, opposed lugs adjacent said end portion of the latch member and rockably mounted in said sector-shaped openings, the second end portion of the latch member being joggled outwardly relative to the sleeve to form a finger piece adjacent the axial sleeve opening for operating the latch member, and a spring acting between said sleeve and said second end portion to bias the latch into the engaged position.

Claim 5

A safety seat belt assembly incorporating a two-part separable buckle of which the first part, to which lap and diagonal straps are adapted to be connected, has a readily releasable engagement with a second part which is adapted to be connected to a floor anchorage, the first part comprising a headed shank and a circumferential shoulder around said shank behind said head, and the second part comprising a rigid sleeve having laterally extending parallel flanges, said sleeve having an axial opening for receiving the shank, aligned sector-shaped opening in said flanges, an elongated latch member having an end portion adapted to engage the shoulder on said shank the latch member extending from said end portion in the direction of the axial sleeve opening, opposed lugs adjacent said end portion of the latch member and rockably mounted in said sector-shaped openings, the second end portion of the latch member being joggled outwardly relative to the sleeve to form a finger piece adjacent the axial sleeve opening for operating the latch member, and a spring acting between said sleeve and said second end portion to bias the latch into the engaged position.

Claim 6

A safety seat belt assembly as in claim 3 wherein a bolt is rigidly fixed to the sleeve, the bolt being adapted to secure the second part of the buckle to the anchorage.

Claim 7

A safety seat belt assembly incorporating two-part part separable buckle of which the first part, to which lap and diagonal straps are adapted to be connected, has a readily releasable engagement with a second part which is adapted to be connected to a floor anchorage, the first part comprising a headed shank and a circumferential shoulder behind said head, and the second part comprising a rigid sleeve having laterally extending parallel flanges, an axial opening at one end of said sleeve for receiving said headed shank, a bolt rigidly fixed to the other end of said sleeve, the bolt being adapted to secure the second part of the buckle to the anchorage, aligned openings in said flanges, and a spring-pressed latch member having opposed lugs rockably mounted in said aligned openings for bringing an end portion into engagement with said shoulder in the first part within said sleeve, said latch member extending from said end portion to a position adjacent said axial opening and outside of said sleeve for operating the latch member.

Claim 8

A safety seat belt assembly incorporating two-part part separable buckle of which the first part, to which lap and diagonal straps are adapted to be connected, has a readily releasable engagement with a second part which is adapted to be connected to a floor anchorage, the first part comprising a headed shank and a circumferential shoulder behind said head, and the second part comprising a rigid sleeve having laterally extending parallel flanges, an axial opening at one end of said sleeve for receiving said headed shank, a bolt rigidly fixed to the other end of said sleeve, the bolt being adapted to secure the second part of the buckle to the anchorage, aligned openings in said flanges, and a spring-pressed latch member having opposed lugs rockably mounted in said aligned openings for bringing an end portion into engagement with said shoulder in the first part within said sleeve, said latch member extending from said end portion to a position adjacent said axial opening and outside of said sleeve for operating the latch member.
