Abstract

A latch plate assembly (10) comprising: a plate (12) having a tongue (14) formed at one end (16) thereof, a back portion (18) opposite the tongue (14) and a first opening formed in the back portion (18); a web guide (40), is positioned about the back portion (18) which includes an elevated member (44) spaced above the back portion (18) and a lower member (42) positioned below the back portion (18). The members (42, 44) cooperate to define a web guide slot (46) which laterally extends relative to the plate (12) to receive the seat belt webbing (36). The elevated member (44), includes a sloped surface (48) extending away from the first opening (34) and a first engagement surface (50) extending laterally positioned across a rear side of first opening (34). The latch plate assembly further includes: a cover (70) slidingly received about plate (12) relative to the web guide ( 40). The cover comprising first and second side members (72a, 72b), a top crossmember (74) and a bottom crossmember (76), each of the first and second side members (72a, 72b) including a slot (78a, 78b) through which is received a corresponding side (32a, 32b). The top crossmember (74) includes a rib (82) which extends into the first opening (34) so as to engage a front side of the first opening (34) when the cover (70) is slid forward on the plate (12) and to compressively load the seat belt webbing (36) against the first engagement surface (50) when the cover (70) is moved rearwardly.

Claims

1. A latch plate assembly (10) comprising:

a plate (12) having a tongue (14) formed at one end (16) thereof, and a back portion (18) opposite the tongue (14);

the tongue (14) including means for receiving (20) a locking mechanism of a cooperating buckle, such receiving means (20) including at least one aperture (22) formed in the tongue (14);

the back portion (18) including a front cross bar (31) and a rear cross bar (30), sides (32a, 32b) joining the front cross bar (31) with the rear cross bar (30) and a first opening (34) of sufficient size to receive seat belt webbing (36);

a web guide (40), insert molded about the rear cross bar (30) and including an elevated member (44) spaced from a base member (42) and, spaced from the rear cross bar (30), the base and elevated members (42,

     44) cooperating to define a web guide slot (46), positioned above a plane containing the rear cross bar (30) and laterally extending to receive the seat belt webbing (36);

the elevated member (44), including a sloped surface (48) extending away from the first opening (34) and a first engagement surface (50) extending laterally across the rear cross bar (30) at the rear of the first opening (34);

a cover (70), slidingly received about plate (12), comprising;

first and second side members (72a, 72b), a top crossmember (74) and a bottom crossmember (76), each of the first and second side members (72a, 72b) including a slot (78a, 78b) through which is received a corresponding side (32a, 32b) of the plate (12);

the top crossmember (74) joining the first and second side members (72a, 72b) and slidably received relative to a top surface (80) of the front cross bar (31);

the top crossmember (74) includes a rib (82) extending into the first opening (34) so as to engage a front side of the first opening (34) when the cover (76) is slid forward on the plate (12) and to compressively load the seat belt webbing (36) against the first engagement surface (50) when the cover (70) is moved rearwardly, the top crossmember (74) including reinforcement means (90) for stiffening same, such reinforcement means (90) including a bar (92) within the top crossmember (74);

the bottom crossmember (76), joins the first and second side members (72a, 72b) and is spaced (98) from the underside (94) of the plate (12) and the bottom (96) of the rib (82) such that the webbing (36) may extend through the first opening (34) and extend through the underside space (98) forward of the bottom crossmember (76) to exert a rearward pressure thereon.

2. A latch plate assembly (10) comprising:

a plate (12) having a tongue (14) formed at one end (16) thereof, a back portion (18) opposite the tongue (14) the back portion (18) including a front cross bar (31) and a rear cross bar (30), sides 32a, 32b) joining the front cross bar (31) with the rear cross bar (30), and a first opening formed in the back portion.(18);

a web guide (40), is positioned about the back portion (18) and includes an elevated member (44) spaced above the back portion (18) and a lower member (42) positioned below the back portion (18), the lower and elevated members (42,

     44) cooperating to define a web guide slot (46) laterally extending to receive the seat belt webbing (36);

the elevated member (44), including a sloped surface (48) extending away from the first opening (34) and a first engagement surface (50) extending laterally across a rear side of the first opening (34);

the latch plate assembly further includes;

a cover (70) slidingly received about the plate (12) relative to the web guide (40) comprising;

first and second side members (72a, 72b), a top crossmember (74) and a bottom crossmember (76), each of the first and second side members (72a, 72b) including a slot (72a, 78b) through which is received a corresponding side of said plate (32a, 32b);

the top crossmember (74) includes a rib (82) extending into the first opening (34) so as to engage a front side of the first opening (34) when the cover (70) is slid forward on the plate (12) and to compressively load the seat belt webbing (36) against the first engagement surface (50) when the cover (70) is moved rearwardly.

3. The assembly as defined in claim 2 wherein the top crossmember (74) including reinforcement means (90) for stiffening same such reinforcement means (90) including a bar (92) within the top crossmember (74).

4. The assembly as defined in claim 3 wherein the reinforcement bar (92) is insert molded into the top crossmember (74).

5. The assembly as defined in claim 4 wherein the web guide slot (46) is positioned above a plane containing the rear cross bar (30).

6. The assembly as defined in claim 5 wherein the bottom crossmember (76) is spaced (98) from the underside (94) of the plate (12) and a bottom (96) of the rib (82) such that the webbing (36) may extend through the first opening (34) through the underside space (98), forward of the bottom crossmember (76), so that when the webbing is bent rearwardly the webbing exerts a rearward pressure thereon causing the cover (70) to slide toward the web guide (40).
