In automotive terms, these components are parts of the mechanism and structure that mount and adjust car seats. Let's break down what each part typically refers to:

1. Slider: The slider is part of the seat adjustment system that allows the seat to move forwards or backwards. It usually consists of a pair of metal tracks that are fixed to the car floor and the seat itself. These tracks contain mechanisms that allow them to slide along each other, usually controlled by a lever or a bar under the seat. This adjustment lets drivers and passengers find a comfortable seating position and ensures that drivers can reach the pedals comfortably.

2. Side Mounts: Side mounts are used in some car seat installations, especially in sportier or racing cars, to attach the seat to the car's chassis or floor. Unlike the more common bottom mount seats, which are secured from underneath, side mounts are brackets that attach to the side of the seat and then to the car's chassis. This often provides a more rigid and secure mount, which is particularly important in high-performance or racing situations where safety and the absence of seat movement are crucial.

3. Seat Base Bracket: The seat base bracket is the part that connects the seat to the car's floor, providing a mounting point for the seat. It can be a flat platform or a more complex frame that the seat bolts onto. The bracket ensures that the seat is securely attached to the car and can also provide the mounting points for sliders and other adjustment mechanisms. In some cases, the bracket may also include or integrate with the vehicle's specific attachment points, such as those required for airbag sensors or electronic connections for power seats.

These components are essential for ensuring that car seats are secure, adjustable, and meet the ergonomic needs of drivers and passengers. They are also crucial for safety, as they ensure that the seat remains in place in the event of an accident.
