以色列采购需求：i-size 婴儿背带、新生儿汽车安全座椅、0+ 组汽车安全座椅、可折叠汽车安全座椅、带顶篷的婴儿汽车安全座椅、婴儿汽车安全座椅

I would like to inquire about the safety of using the infant carrier without the base. Specifically, I need clarification on whether it's safe to drive with it this way and the correct method for securing the seatbelt as per the guidelines. Ensuring the safety of the child during travel is my top priority, so detailed instructions on this matter would be greatly appreciated. Additionally, I'm interested in purchasing the base for this infant carrier. Could you please provide information on where I can buy it in Israel? Any recommendations for local retailers or online stores would be very helpful. Thank you for your assistance!
