Bumpers: Its Importance, Functions and Where to Find Replacement Bumpers

Bumpers are one of the most essential auto parts. They serve both an aesthetic and practical function. They are also important safety features. Bumpers are made of heavy sheet metal and are mounted on the front and rear of the car. Bumpers are bent and formed into specific shapes in order to absorb and deliver momentum during a collision. In the event of a collision, the bumper absorbs some of the impact, which decreases damage to the car and its occupants. It also protects the front of the car by diverting all of the car’s momentum to the object with which it has collided. The bumper is mounted to the car’s chassis with special impact absorbers. These shock absorbers are often spring loaded. In slow speed collisions, this allows the bumper to compress, and then extend back to its original position. All bumpers are designed to absorb the energy of the impact. They do this through a series of valves and air chambers.

Some car bumpers have hydraulic chambers. In the event of a collision, the absorption unit allows air and/or hydraulic fluid to pass through small openings. Forcing the air/fluid through the valve openings absorbs the energy from the collision. The bumper’s job is to minimize damage, primarily to the occupants of the vehicle and to the vehicle itself. US law requires cars to pass special crash tests at various speeds.

In order to pass, the car’s damage level during the crash must be below a specific dollar level. This protects the consumer and is very important for keeping the cost of automobile insurance to a minimum. Sometimes bumpers are constructed with built-in “crumple zones.” Crumple zones are designed to absorb impact; they will flex on impact. As the metal flexes, the action of the bending metal converts the kinetic energy of the car into heat. Kinetic energy is the energy an object possesses while it is in motion.

GM automobiles are all equipped with capable bumpers that help protect the vehicle from serious damages in the event of a collision. However, like all auto parts, bumpers will eventually get damaged or defective due to accidents, wear and tear and corrosion. Usually such damages will weaken the bumper’s ability to absorb the shock of collision. Thus, it is a necessity to replace old and damaged bumpers with a new one. Replacement GM Bumpers can be purchased from auto parts dealers everywhere. However, to be sure of quality and durability, purchase only from a reliable and trustworthy auto parts store with an established reputation.

Auto Detailing – Save Your Knees and Find a Knee Pad Solution

A couple of years ago, I talked to a gentleman at Starbucks who was on disability. He had worked for a carpet installation company and had blown out his knees, both of them and could hardly walk, and one could not be repaired, although they tried by putting in some titanium. He admitted it did help for a while, but his knee was simply to tore up inside. You see, those that install carpets often use their knees to help pound the nails in the baseboard during installations as he explained it to me. Interestingly enough, I understand how important it is to save your knees because previously I was a tack star and later had raced street motorcycles, and also had done quite a bit of auto detailing. Okay so let’s talk shall we?

If you are in the auto detailing business you will be on your knees quite a bit cleaning wheels, under carriages, and putting on wax of vehicles which are very low to the ground, like most exotic sports cars. This means you have to get down and dirty, but in doing so you will be working in a parking lot if you are doing mobile detailing with gravel around, or you will be working on a cement floor inside of an auto detailing shop, those are very hard surfaces, and they can be quite challenging if you are in that position on your knees for long periods of time.

There are several auto detailing catalogs which have very small cushioned mats which are between six and 8 inches wide and 2 feet long with a handle on them, on one end. These work perfectly, and they are an ideal solution for an auto detailer. Best of all you can clip them to a work cart using a carabiner that rock climbers use. Another strategy is to get ahold of the type of knee pads that soccer players use from a sports store. Although they are not as good, they will save your knees. If you are an auto detailer you may put one on only one knee, and kneel down on that each time. Every few days you might wear it on the other knee, so you are not favoring one leg over the other. Always buy the fabric washable kind.

It’s amazing how simple things and proper ergonomic procedures can help you in your auto detailing this. If you are detailing aircraft, especially light aircraft, or small business jets, it is often very hard to clean the underbelly, or the bottom of the wings with one knee on the ground, either on the flight line or in a hangar on the hangar floor. Protect your knees so you don’t have to become a disabled auto detailer. Please consider all this and think on it.
