Chapter 5: Seat Belt Systems Without Pre-Crash Locking Features

5-2National CPS Certification Training - April 2007 (R1010) Chapter Objectives Identify seat belt systems without a pre-crash locking feature Identify four approved additional pre- crash locking steps Identify how to secure a CR when the seat belt system requires an approved additional step for pre-crash locking

5-3National CPS Certification Training - April 2007 (R1010) Latchplates Without Pre-Crash Locking Features: Sliding Latchplate Found only on lap-shoulder systems

5-4National CPS Certification Training - April 2007 (R1010) Sewn-On Latchplate Found on lap-only and lap/shoulder systems Lap and Shoulder Lap Only

5-5National CPS Certification Training - April 2007 (R1010) Emergency Locking Retractor (ELR) Looks like a switchable retractor but does not have the ability to switch Locks in a sudden stop, turn, or crash Is comfortable and safe for adults When webbing is pulled all the way out, it still moves in and out freely Cannot be used to install CR without an approved additional step or locking latchplate

5-6National CPS Certification Training - April 2007 (R1010) Activity 1: Identifying Latchplates and Retractors Latchplate  Locking  Switchable  Sliding  Sewn-on Retractor  ALR  Switchable  ELR  None Vehicle # _______ Seating position _______

5-7National CPS Certification Training - April 2007 (R1010) When Neither Latchplate Nor Retractor Stays Pre-crash Locked Use one of the four approved additional steps to installation a CR: ▪Locking clip/lockoff ▪Belt shortening clip ▪Flip latchplate ▪Twist buckle stalk

5-8National CPS Certification Training - April 2007 (R1010) The Locking Clip Pre-crash device works until retractor activates in a crash Creates a fixed length of webbing in the lap belt Only used on a lap- shoulder belt with a retractor Found on all CRs when purchased

5-9National CPS Certification Training - April 2007 (R1010) CR Lock-Off

5-10National CPS Certification Training - April 2007 (R1010) When to Use a Locking Clip ALL three conditions must be present: Lap-shoulder belt is all one piece of webbing ELR is in place Sliding latchplate does not lock pre- crash

5-11National CPS Certification Training - April 2007 (R1010) Lap-Shoulder Belt Only - How to Use a Locking Clip Route belt through correct belt path and buckle Apply weight to CR while pulling shoulder webbing to remove lap belt slack Pinch and hold both pieces of webbing together and unbuckle Attach clip within 1 inch of latchplate and re- buckle Test for tightness

5-12National CPS Certification Training - April 2007 (R1010) ELR and Sewn-On Latchplate Lap belt only or lap portion only of lap- shoulder with sewn-on latchplate The belt-shortening clip “takes the retractor out of the picture” and serves as the locking part Pre-crash locking is not possible without the belt-shortening clip The belt-shortening clip clamps off all excess webbing to create a fixed length of webbing in the lap portion of the seat belt

5-13National CPS Certification Training - April 2007 (R1010) The Belt-Shortening Clip Must be purchased where vehicles are sold or made Firmly ties off and locks fully extended seat belt webbing to provide a fixed lap belt length Takes the place of the retractor Placed near the retractor (on the door side) Should be tested for tightness Can increase injury risk if used incorrectly Used as a last resort

5-15National CPS Certification Training - April 2007 (R1010) Locking Clip or Belt- Shortening Clip Locking Clip/Lock-offBelt-Shortening Clip Found on every CRPurchased from auto dealer only Used with lap-shoulder belt with ELR and sliding latchplate Used on lap portion of seat belt with ELR and sewn-on latchplate Used only on seat belt with retractor as backup Used in place of retractor — no retractor backup available Never used to replace belt- shortening clip or to shorten a seat belt Can be used in place of regular locking clip

5-16National CPS Certification Training - April 2007 (R1010) Activity 3: What would you do to provide a pre- crash locked seat belt?

5-17National CPS Certification Training - April 2007 (R1010) Problem Solving: Locking Latchplate Slips Webbing loosens when firmly pulled up CR moves more than 1 inch ▪Flip the latchplate to change angle - OR ▪Twist the buckle stalk to shorten buckle webbing - OR ▪Use a locking clip if it is a lap and shoulder belt as a last resort Check for tightness

5-18National CPS Certification Training - April 2007 (R1010) When Do You Flip the Latchplate? Locking latchplate doesn't stay locked when it should: Solution: Unbuckle and flip Tilt Flat

5-19National CPS Certification Training - April 2007 (R1010) When Do You Twist the Buckle Stalk? Helpful when the buckle does not lie flat, is in the belt path, or does not allow the lockoff to be secured Twisting the buckle will make the webbing shorter This will make the buckle lower 3 twists maximum

5-20National CPS Certification Training - April 2007 (R1010) Locking Clips and Belt-Shortening Clips Instructor Demonstration Demonstrate: ▪Locking clip/lock-off ▪Belt-shortening clip ▪Flipping a seat belt latchplate ▪Twisting a seat belt buckle Install a CR using: ▪Locking clip/lock-off ▪Belt-shortening clip ▪Flipped seat belt latchplate ▪Twisted seat belt buckle

5-21National CPS Certification Training - April 2007 (R1010) Review: The Four Accepted and Approved Additional Steps Lap/shoulder belt has ELR + free sliding latchplate: Use a locking clip Lap-only belt has ELR and sewn-on latchplate: Use another seating position to secure CR or use a belt-shortening clip Locking latchplate slips: Option 1) flip latchplate, Option 2) twist buckle stalk, or Option 3) use a locking clip Buckle on a long stalk: Twist buckle stalk (if permitted by vehicle manufacturer) to shorten

5-25National CPS Certification Training - April 2007 (R1010) Congratulations! You can now identify any vehicle retractor- latchplate combination as long as you take your time and follow the steps you have learned: There are four ways to lock a belt system: 1.At the latch plate 2.At the retractor 3.Locking clip 4.Belt shortening clip You have the tools to be able to pre-crash lock virtually any seat belt.

5-26National CPS Certification Training - April 2007 (R1010) Chapter Review How can I secure a CR when the seat belt system requires an approved additional step for pre-crash locking? When do I flip the latch plate? What does ELR stand for? What are the four ways to pre-crash lock a seat belt system?
