That is, the projection of the upper surface 323 of the first locking portion 320 of the first anchor 32 in a plane is not overlapped over the second surface 203, and the projection of the upper surface 341 of the second locking portion 340 of the second anchor 34 in a plane is not overlapped over the second surface 203.

Referring back to FIGS. 2, 4-5, FIG. 2, FIGS. 4-5 shows the restraint assembly 10 at an assembled position or the second assembled position according to one or more embodiments of the present disclosure. According to one or more embodiments, the connector 30 may be movable from a first assembled position as shown in FIG. 6 to the second assembled position along the direction L2. The term of an assembled position in this application refers to the location where the connector 30 and the vehicle part 20 are aligned to receive the fastener, and the first anchor 32 and the second anchor 34 contact the vehicle part 20 such that the connector 30 and the vehicle part 20 are aligned automatically. More specifically, the second assembled position is the position when the connector 30 is assembled onto the vehicle part 20, the first anchor 32 and the second anchor 34 are inserted into the first and second slots 22, 24, respectively, and the second assembling hole 310 is aligned with the first assembling hole 210. Further, the first anchor 32 is positioned in the second cutout 224 of the first slot 22.

Further referring to FIGS. 4-5 and FIGS. 3A-3B, when the connector 30 is moved from the first assembled position to the second assembled position, the first anchor 32 is positioned adjacent to or contacts the slot wall 221 of the first slot 22, and the second anchor 34 is positioned adjacent to or contacts the slot wall 241 of the second slot 24 such that the second assembling hole 310 is aligned with the first assembling hole 210. Particularly, the first anchor 32 is positioned in the second cutout 224 and contacts the slot wall 221. Accordingly, even if the restraint assembly 10 is tilted at the assembled position, the second assembling hole 310 will not be offset relative to the first assembling hole 210 under the gravity since the first anchor 32 contacts the slot wall 221 of the first slot 22, and the second anchor 34 contacts the slot wall 241 of the second slot 24 such that the movement of the connector 30 relative to the vehicle part 20 along the direction L1 and the direction L2 may be restricted.

As depicted in FIG. 4, the first cutout 222 of the first slot 22 has a width W1 in the direction L1, while the second cutout 224 has a width W2 in the direction L1, and the first locking portion 320 has a width W3 in the direction L1. In one or more embodiments, the width W3 is greater than the width W2 but less than the width W1. The second slot 24 has a width W4 in the direction L2, and the second locking portion 340 has a width W5 in the direction L2. In one or more embodiments, the width W4 is greater than the width W5. When the connector 30 is moved from the first assembled position to the second assembled position, the first anchor 32 is received in the second cutout 224, and the upper surface 323 of the first locking portion 320 is opposite to the second surface 203 of the vehicle part 20. Further, when the connector 30 is moved from the first assembled position to the second assembled position, the second anchor 34 is received in the second slot 24, and the upper surface 341 of the second locking portion 340 is opposite to the second surface 203 of the vehicle part 20. Another advantage of the restraint system of the present disclosure is that the first locking portion 320 and the second locking portion 340 may restrict the movement of the connector 30 relative to the vehicle part 20 in the direction perpendicular to the assembling surface 301 of the connector 30 at the second assembled position.

As depicted in FIG. 5, the upper surface 323 of the first locking portion 320 and the upper surface 341 of the second locking portion 340 are spaced at a distance from the second surface 203 of the vehicle part 20, respectively at the second assembled position. It will be understood that based on specific application, the upper surface 323 of the first locking portion 320 and the upper surface 341 of the second locking portion 340 may also be configured to contact the second surface 203 of the vehicle part 20.

In addition, as depicted in FIG. 3 and FIG. 5, in one or more embodiments, the base 31 of the connector 30 may also be configured to include a first portion 312 and a second portion 314 extending from the first portion 312 at an angle relative to the first portion 312. As depicted in FIG. 3, the second assembling hole 310 is positioned on the first portion 312. The connecting hole 318 is configured to receive a tether 42 of the side curtain airbag 40 and is positioned on the second portion 314. The first anchor 32 and the second anchor 34 may be positioned on the first portion 312, and the second anchor 34 is closer to the second portion 318 than the first anchor 32. Since the second portion 314 is positioned at an angle a relative to the first portion 312, if the second portion is experienced pressure, the second end portion 306 of the connector 30 may be deflected away from the first surface 201 of the vehicle part 20 during assembling process. If the second portion 314 is pulled, the first end portion 304 of the connector 30 may be deflected away from the first surface 201 of the vehicle part 20. This deflection may be at least partially mitigated via the configuration of the first anchor 32 and the second anchor 34. More specifically, when the second portion 314 is under a pressure, the first locking portion 34 of the first anchor 32 may inhibit this deflection. When the second portion 314 is pulled by a force, the second anchor 34 may inhibit this deflection. In addition, in the instance that the connector 30 and the vehicle part 20 are at the assembled position and the assembling surface is of an angle relative to the vehicle floor or substantial perpendicular to the vehicle floor, the connector 30 may be fell off due to the gravity during assembling if only the first anchor 32 is present. Therefore, it is not easy to align the second assembling hole 310 with the first assembling hole 210 of the vehicle part 20. While the second anchor 34 may coordinate with the second slot 24 to prevent the connector 30 from moving, and thus the second assembling hole 310 may be automatically aligned with the assembling hole 210 of the vehicle part.

The connector and the restraint assembly of the present disclosure have simple structure and are able to align the connector with the vehicle part easily during the assembly process.

In one or more embodiments, the present invention as set forth herein is believed to have overcome certain challenges associated with the restraint assembly.
