WHS-P Plastic Bone Rear Window wipers

1. Introduction to Rear Window wiper blades

The WHS-P Plastic Bone Rear Window Wiper is designed to provide efficient rear windshield cleaning with a lightweight yet durable frame structure. Rear window wipers are an essential part of modern vehicle visibility systems, helping drivers maintain a clear view through the rear windshield during rain, snow, or dusty road conditions.

Vehicles with vertical or semi-vertical rear glass surfaces tend to accumulate moisture and debris quickly. Unlike front windshields, the rear window receives limited airflow while driving, making mechanical wiping necessary to maintain visibility.

Rear window wipers are widely used on the following vehicle categories:

• Hatchbacks

• Sport Utility Vehicles (SUVs)

• Crossovers

• Multi-Purpose Vehicles (MPVs)

• Station wagons

• Light commercial vans

The WHS-P rear wiper blade integrates a plastic bone frame structure and flexible rubber wiping element, offering reliable performance with reduced weight and improved durability.

2. What Is a Plastic Bone Rear Window Wiper?

A plastic bone rear window wiper is a frame-style wiper blade featuring a reinforced plastic skeletal structure that supports the rubber wiping strip. The “bone” structure refers to the articulated joint system that distributes pressure evenly across the blade.

This design allows the blade to follow the curvature of the rear windshield, ensuring consistent contact with the glass surface.

Main Structural Components

Plastic Bone Frame
A lightweight structural frame that supports the wiping element while maintaining flexibility.

Rubber Wiping Blade
A flexible rubber strip responsible for removing water, dirt, and debris from the glass.

Spring Steel Reinforcement
Internal metal supports maintain uniform pressure across the blade length.

Connector Adapter
A standardized mounting system allows easy attachment to the rear wiper arm.

The combined structure ensures efficient wiping performance and improved durability.

3. Key Features of the WHS-P Rear Window Wiper

Improved Rear Visibility

A properly functioning rear window wiper helps maintain a clear rear windshield, allowing drivers to safely monitor traffic conditions behind the vehicle.

This is particularly important during:

• Heavy rain

• Snow or frost conditions

• Mud and road spray exposure

• Urban traffic environments

Lightweight Yet Strong Construction

The combination of lightweight plastic materials and reinforced structure provides:

• Strong frame stability

• Reduced mechanical stress

• Efficient wiping motion

This balance improves both durability and performance.

Corrosion and Weather Resistance

Plastic frame construction protects the wiper blade from environmental damage caused by:

• Moisture

• Road salt

• Humidity

• UV exposure

This improves the long-term reliability of the rear wiper system.

Easy Installation and Replacement

Most plastic bone rear wipers use clip-on or hook-type connectors, enabling fast installation without special tools.

This makes maintenance simple for vehicle owners and service technicians.

5. Typical Vehicle Applications

The WHS-P plastic bone rear window wiper is suitable for various passenger vehicles that require rear windshield cleaning.

Vehicles with steeper rear window angles benefit most from rear wiper systems.

6. Common Rear Wiper Blade Sizes

Rear window wiper blades are typically smaller than front windshield wipers.

Choosing the correct blade size ensures optimal glass coverage and efficient wiping performance.

7. Typical Technical Specifications

8. Rear Wiper Blade Maintenance Tips

Regular maintenance helps ensure reliable performance and extend blade lifespan.

Recommended maintenance practices include:

• Cleaning the rubber blade periodically

• Removing debris from the rear windshield surface

• Avoiding operation on dry or dusty glass

• Checking blade flexibility regularly

• Replacing the blade every 6–12 months

Routine care prevents streaking and maintains optimal rear visibility.

9. Importance of Lightweight Rear Wiper Designs

Modern vehicles increasingly prioritize lightweight automotive components to improve efficiency and reduce mechanical strain. Lightweight rear wiper designs like the WHS-P Plastic Bone Rear Window Wiper help reduce stress on the rear wiper motor while maintaining durable wiping performance.

With its lightweight structure, corrosion-resistant plastic frame, and flexible rubber blade, the WHS-P rear window wiper provides a practical solution for maintaining rear windshield clarity and improving driving safety.
