Description

  The present invention relates to a headlining attached to a vehicle interior ceiling portion of a vehicle, and an interior structure including the headlining.

  A headlining is attached to the interior side of the vehicle ceiling from the interior of the vehicle to cover the entire interior of the vehicle ceiling. The left and right edges of the head lining are covered with, for example, an extending portion extending from the weather strip, and the edges are directly attached to the base portion where the weather strip and the vehicle body are attached in order to absorb molding errors and assembly errors. It may be attached without touching.

  In addition, a front pillar trim is attached to the A pillar to cover the vehicle interior side of the A pillar. The front pillar trim is usually made of a hard synthetic resin material or the like, and its upper end overlaps with the front part of the head lining and is attached so as to be connected in appearance.

  The front pillar trim and the head lining are overlapped obliquely and with a three-dimensional curved surface, and it is difficult to match the shapes of the overlapped portions, and a gap may be formed between them. Therefore, conventionally, a pressing piece or the like is provided on the back side of the head lining to push the head lining to the vehicle interior side, and the head lining is brought into close contact with the inner surface of the pillar trim to eliminate the gap.

  On the other hand, a curtain airbag device may be provided in a vehicle. The curtain airbag device is a head protection device that deploys the airbag in a curtain shape along the window, and is usually provided inside the left and right ends of the headlining, and operates by pushing the ends of the headlining open. .

  However, the pressing piece only applies a pressing force to the head lining in one direction from the inside, and the gap formed at a position deviating from the pressing direction cannot be effectively eliminated. Therefore, a gap may remain between the head lining and the pillar trim, which is not preferable from the viewpoint of appearance, and the mounting process for attaching the pressing piece to the inside of the head lining takes time and cost. Further, in a vehicle equipped with a curtain airbag device, the pressing piece cannot be provided at an appropriate position, and sometimes it is necessary to change the pasting location for each vehicle type specification.

  It is an object of the present invention to provide a head lining that is easy to attach and is in close contact with a pillar trim and does not generate a gap, and a vehicle interior structure using the head lining.

  In order to solve the above-described problems, the present invention is configured as follows.

  The head lining is formed in a shape corresponding to the vehicle interior ceiling of the vehicle, and has an assembly portion to which the edge of the front pillar trim is assembled at least at the front left and right end portions. The front pillar trim is an interior material attached to the front pillar.

  The assembly portion has an overlapping portion that is convexly curved toward the indoor side and overlaps the front pillar trim. A front pillar trim is superimposed on the head lining at the overlapping portion with the front pillar trim facing the room.

  In the vicinity of the assembly portion, a fixing portion and a protrusion are provided. The fixing portion is provided at a position located on the vehicle center side along the vehicle width direction from the overlapping portion, and fixes the headlining to the vehicle body. The fixing portion is, for example, a mounting base portion of a sun visor.

  The protrusion is provided at a location where the line extending from the fixed portion outward in the vehicle width direction and the edge of the head lining intersect, or in the vicinity of the intersection. The protrusion is formed by projecting the edge of the head lining outward, and when the head lining is attached to the ceiling of the passenger compartment, a predetermined portion of the vehicle main body, for example, a weather strip base that is an attachment portion between the weather strip and the vehicle body, is provided. It has a protruding height that is pressed by force. The protrusion is formed in a pair with the fixed portion.

  Further, a first weakened portion and a second weakened portion are formed in the assembled portion. The first weakening portion is formed along the overlapping portion in the region including the overlapping portion. For example, the first weakening portion has a thin head lining to weaken a resistance against a deformation force. Thereby, the overlapping portion is easily deformed. In other words, the head lining protrusion is pushed from the outside in the vehicle width direction toward the center side by a predetermined force on the vehicle body, while the center side in the vehicle width direction is fixed by the fixing portion so that it protrudes indoors. The head lining is bent so as to be pressed against the inside of the pillar trim, and the head lining is along the inside of the pillar trim.

  The second weakened portion is formed continuously with the first weakened portion so as to intersect the line connecting the fixed portion and the protrusion. The second weakened portion is formed by thinning the head lining in the same manner as the first weakened portion. As a result, the assembled portion is easily deformed around the second weakened portion, and when the assembled portion is pressed from both sides in the vehicle width direction, the assembled portion is curved inward. In the present invention, the pillar is not limited to the front pillar.

  Further, the vehicle interior structure according to the present invention includes the head lining, a pillar trim provided on the head lining, a sun visor fixture for fixing the head lining fixing portion, and a side door opening edge of the vehicle. It is provided and is comprised from the weather strip which the protrusion of a headlining contacts.

  The vehicle headlining and the vehicle interior structure according to the present invention have the following effects.

  Since the head lining is deformed so as to be pressed against the curved shape of the inner surface of the pillar trim and is in close contact with the inner surface of the pillar trim, no gap is formed between the head lining and the pillar trim. Since no pressing member is required as a separate member, the assembly work of the interior structure is facilitated.

  The assembly part is pressed in the width direction between the protrusion and the fixed part, and the rigidity in the vicinity of the assembly part is increased by the influence of the tension rigidity. Since the first and second weakened portions are partially formed on the headlining, the strength of the entire headlining does not decrease.

  There is no need to change the headlining specifications significantly, and the cost is not increased. The pillar trim and weatherstrip do not need to be changed and can be used as they are. Since the edge of the head lining is pressed against the vehicle main body only at the projection, even if a curtain airbag device is provided, there will be no significant hindrance to the deployment of the curtain airbag device.

The weather strip 34 is fixed by fitting the mounting base 40 to the edge of the door opening, that is, the edge of the roof side rail 32 in FIG. The door contact portion 36 is formed in a hollow shape, and comes into contact with the periphery of the side door 18 when the side door 18 is closed. The extending portion 38 extends from the door contact portion 36 toward the passenger compartment, and covers and contacts the end portion of the headlining 30.

  Next, the headlining 30 will be described.

  FIG. 2 shows the entire headlining 30. FIG. 2 shows the headlining 30 from above. The headlining 30 is formed in a shape that covers the passenger compartment ceiling 22 in the passenger compartment of the vehicle 10.

  Assembly portions 42 are formed on the front left and right ends of the head lining 30, respectively. The assembling portions 42 are formed symmetrically, and the upper portions of the pillar trims 26 (only shown on the right side) are connected to each. The assembly portion 42 has a curved shape protruding toward the indoor side, and corresponds to the upper end shape of the pillar trim 26.

  In FIG. 1, the assembly part 42 is enlarged and shown. As shown in FIG. 1, the assembly portion 42 is provided with an overlapping portion 44, a first weakening portion 46, and a second weakening portion 48.

  The overlapping portion 44 is formed along the edge of the assembly portion 42 as indicated by the dotted line in FIG. 1. When the head lining 30 and the pillar trim 26 are respectively attached to the vehicle 10, the overlapping portion 44 has the pillar trim 26. Is superimposed on the vehicle interior side.

  The first weakening portion 46 includes the overlapping portion 44, and a region wider than the overlapping portion 44 is formed along the overlapping portion 44. The second weakening portion 48 is formed continuously with the first weakening portion 46 along the longitudinal direction of the vehicle 10, that is, substantially along the extension line in the longitudinal direction of the A pillar 14. The first weakened portion 46 and the second weakened portion 48 are formed by reducing the thickness width from the thickness of other portions of the headlining 30. Note that the first weakened portion 46 and the like may be formed by other methods as long as the strength is reduced instead of reducing the thickness.

  The head lining 30 is formed with a fixing hole 50 as a fixing portion and a protrusion 52. The fixing hole 50 is formed at a position a predetermined distance a away from the overlapping portion 44 toward the vehicle center along the vehicle width direction. The fixing hole 50 is an attachment hole for allowing the attachment tool 29 of the sun visor 28 to pass therethrough, and the periphery of the fixing hole 50 is secured to the vehicle interior ceiling portion 22 (the roof panel 12, the roof rail, and the roof bar (not shown)) by the attachment tool 29. Etc.). The sun visor 28 and the fixture 29 are conventionally used.

  The protrusion 52 is formed in the vicinity of a position where a straight line extending outward in the vehicle width direction from the fixing hole 50 and the edge of the head lining 30 intersect. The protrusion 52 is formed by projecting the edge of the head lining 30 outward. When the head lining 30 is attached to the vehicle interior ceiling 22 and the head lining 30 is fixed by the fixing hole 50, a predetermined portion is formed on the weather strip 34. It has a height that makes contact with force.

  Next, functions and effects of the headlining 30 and the interior structure of the vehicle 10 will be described.

  The headlining 30 is attached to the passenger compartment ceiling 22 of the vehicle 10 with a clip or the like. Further, the right fixture 29 is passed through the right fixing hole 50 of the headlining 30, and the right sun visor 28 is assembled to the vehicle interior ceiling portion 22.

  The right end edge of the head lining 30 is assembled so as to be positioned on the upper portion of the extending portion 38 of the weather strip 34. Then, the protrusion 52 comes into contact with the mounting base 40 of the weather strip 34. Since the protrusion 52 is pressed against the mounting base 40 with a predetermined force, a compression force that compresses the assembly portion 42 in the vehicle width direction acts between the fixing hole 50 and the protrusion 52. Therefore, the assembly portion 42 is urged by the second weakening portion 48 in a direction in which the sectional curvature of the assembly portion 42 in the vehicle width direction is reduced.

  Next, the pillar trim 26 is attached to the A pillar 14 as shown in FIG. Then, the upper end of the pillar trim 26 is pressed against the overlapping portion 44 of the headlining 30 from the indoor side.

  The assembly portion 42 is pressed indoors by the protrusion 52, and the overlapping portion 44 is easily deformed by the first weakening portion 46, so that the overlapping portion 44 is pressed against the inner surface of the pillar trim 26, It deforms along the upper end of the pillar trim 26.

  As a result, the headlining 30 and the pillar trim 26 are in close contact with each other and are connected without a gap, so that the appearance of fitting is improved. Further, since the assembly portion 42 is pressed between the protrusion 52 and the fixing hole 50 so that the interval in the vehicle width direction is narrowed, the rigidity of the assembly portion 42 continuous to the pillar trim 26 is increased.

  Since the second weakening portion 48 is provided between the fixing hole 50 and the protruding portion 52 at the place where the curvature is the largest, that is, the bending is steep, the assembly portion 42 can be bent more effectively, and the pillar trim The headlining 30 can be brought into close contact with the H.26.

  Since the head lining 30 is in contact with the weather strip 34 only at the protrusion 52, the pressing force to the weather strip 34 can be set accurately, and the force required to remove the head lining 30 from the weather strip 34 can be set accurately. it can.

  Since the first weakening portion 46 and the second weakening portion 48 are provided only in the assembly portion 42, the overall rigidity of the head lining 30 is not reduced.

  In the above example, the front pillar 14 has been described as an example, but the present invention is not limited to this.

  The present invention can be used for an interior structure of a vehicle.
