I recently purchased a booster seat for our 4 year old son to use in my vw passat. I get the idea of how the booster seat enables him to use the standard seat belt. But what I don't get is the belt on the bottom /underside of the booster seat. Its only attached to one side and I cant see a purpose for it ? Am I missing something obvious ?
None of my 4 booster seats have this,so after a bit of searching,look at this video just after 3 minute mark. https://www.youtube.com/watch?v=KNXHC_BoCN8&feature=youtube_gdata_player
And for anyone else who is curious,its to change the angle of the seat belt,so that it sits on the child's shoulder.
