Are lap belts in cars safe?

[ghostspirit]

my babys dad wants to get a 7/8 seater car it might end up being an older type car. and im a bit worried about the middle seats only having lap belts..any thoughts on this?

I'm sure we will sort it out. but weather their his/mine/our orchids bloggs kids. I'm not allowing them to use a lap belt I wont even use one.

sorry meant to say Jo bloggs kids
