## Abstract

The present invention relates to a hybrid seat frame for a vehicle and provides a hybrid seat frame for a vehicle including a main frame formed of glass fiber and a reinforced frame formed of carbon fiber to secure stiffness in a direction perpendicular to the longitudinal direction and torsional stiffness and to reduce its weight, thereby improving fuel efficiency of the vehicle.

## Claims

### Claim 1

A hybrid seat frame for a vehicle comprising:
a main frame formed of glass fiber; and
a reinforcing frame coupled to the main frame, the reinforcing frame being formed of carbon fiber.

### Claim 2 (depends on 1)

The hybrid seat frame of claim 1, wherein the glass fiber comprises a polyamide base material and glass short fiber reinforcing material, and the carbon fiber comprises a thermoplastic acryl base material and continuous carbon fiber reinforcing material.

### Claim 3 (depends on 1)

The hybrid seat frame of claim 1, wherein each of the main frame and the reinforced frame has ⊂-shaped cross-section.

### Claim 4 (depends on 3)

The hybrid seat frame of claim 3, wherein reinforcing ribs are disposed on an inner circumferential surface of the main frame.

### Claim 5 (depends on 3)

The hybrid seat frame of claim 3, wherein the main frame is inserted into an inner circumferential surface of the reinforcing frame.

### Claim 6 (depends on 5)

The hybrid seat frame of claim 5, wherein the main frame and the reinforcing frame are coupled to each other by a rivet.

### Claim 7 (depends on 1)

The hybrid seat frame of claim 1, wherein a coupling tool formed of a steel material is disposed on a portion at which the seat frame is connected to the vehicle.
