restrain the shopping JUST on the childrens

[owegen]

Hello,

on my website I just want to allow the shopper to buy the childrens product (in red on the picture).

at the moment on my shop both are available to buy (parents AND childrens) : http://www.mlv-bike.com/j25/index.php/search?keyword=1427&limitstart=0&option=com_virtuemart&view=category

Any idea how I can change it?
